### Rust: Handling File Metadata with `and_then`

Source: https://docs.rs/tauri-plugin-remote-push/1.0.10/tauri_plugin_remote_push/type

Shows how to use `and_then` to chain operations involving file system metadata. This example attempts to get metadata for the root directory and handles potential `IO` errors. It illustrates handling `Result` types returned by file system operations, checking for success or specific error kinds.

```rust
use std::{io::ErrorKind, path::Path};

// Note: on Windows "/" maps to "C:\\"
let root_modified_time = Path::new("/").metadata().and_then(|md| md.modified());
assert!(root_modified_time.is_ok());

let should_fail = Path::new("/bad/path").metadata().and_then(|md| md.modified());
assert!(should_fail.is_err());
assert_eq!(should_fail.unwrap_err().kind(), ErrorKind::NotFound);
```

### Rust: Transposing Result<Option<T>, E>

Source: https://docs.rs/tauri-plugin-remote-push/1.0.10/tauri_plugin_remote_push/type

This example shows the `transpose` method, which converts a `Result` containing an `Option` into an `Option` containing a `Result`. `Ok(None)` becomes `None`, while `Ok(Some(_))` and `Err(_)` are wrapped in `Some`.

```rust
#[derive(Debug, Eq, PartialEq)]
struct SomeErr;

let x: Result<Option<i32>, SomeErr> = Ok(Some(5));
let y: Option<Result<i32, SomeErr>> = Some(Ok(5));
assert_eq!(x.transpose(), y);
```

--------------------------------

### Rust: Get reference to Result value

Source: https://docs.rs/tauri-plugin-remote-push/1.0.10/tauri_plugin_remote_push/type

Shows the `as_ref` method for Rust's Result type. This method converts a reference to a Result (`&Result<T, E>`) into a Result of references (`Result<&T, &E>`), leaving the original Result unchanged. Examples include both Ok and Err variants.

```rust
let x: Result<u32, &str> = Ok(2);
assert_eq!(x.as_ref(), Ok(&2));

let x: Result<u32, &str> = Err("Error");
assert_eq!(x.as_ref(), Err(&"Error"));
```

--------------------------------

### Rust: Convert Result to Option (Ok value)

Source: https://docs.rs/tauri-plugin-remote-push/1.0.10/tauri_plugin_remote_push/type

Illustrates the `ok` method for Rust's Result type. This method consumes the Result and returns an Option containing the success value if it's an Ok variant, otherwise it returns None. Examples show both Ok and Err cases.

```rust
let x: Result<u32, &str> = Ok(2);
assert_eq!(x.ok(), Some(2));

let x: Result<u32, &str> = Err("Nothing here");
assert_eq!(x.ok(), None);
```

--------------------------------

### Rust: Copying and Cloning Result References

Source: https://docs.rs/tauri-plugin-remote-push/1.0.10/tauri_plugin_remote_push/type

These examples demonstrate how to create owned values from references within a `Result`. The `copied` method is used for types that implement `Copy`, while `cloned` is used for types that implement `Clone`. Both methods map a `Result<&T, E>` to a `Result<T, E>`.

```rust
let val = 12;
let x: Result<&i32, i32> = Ok(&val);
assert_eq!(x, Ok(&12));
let copied = x.copied();
assert_eq!(copied, Ok(12));
```

```rust
let val = 12;
let x: Result<&i32, i32> = Ok(&val);
assert_eq!(x, Ok(&12));
let cloned = x.cloned();
assert_eq!(cloned, Ok(12));
```

```rust
let mut val = 12;
let x: Result<&mut i32, i32> = Ok(&mut val);
assert_eq!(x, Ok(&mut 12));
let copied = x.copied();
assert_eq!(copied, Ok(12));
```

```rust
let mut val = 12;
let x: Result<&mut i32, i32> = Ok(&mut val);
assert_eq!(x, Ok(&mut 12));
let cloned = x.cloned();
assert_eq!(cloned, Ok(12));
```

--------------------------------

### Tauri Remote Push Commands (Rust)

Source: https://docs.rs/tauri-plugin-remote-push/1.0.10/src/tauri_plugin_remote_push/commands

This snippet demonstrates how to define asynchronous commands for a Tauri application to interact with the remote push plugin. It includes functions to get a push token and request user permission for notifications. These commands require the `tauri` crate and the `RemotePushExt` trait.

```Rust
use tauri::{command, AppHandle, Runtime};

use crate::{RemotePushExt, Result};

#[command]
pub(crate) async fn get_token<R: Runtime>(app: AppHandle<R>) -> Result<String> {
    app.remote_push().get_token()
}

#[command]
pub(crate) fn request_permission<R: Runtime>(app: AppHandle<R>) -> Result<()> {
    app.remote_push().request_permission()
}
```

--------------------------------

### Rust: Safely Get Ok Value (Nightly)

Source: https://docs.rs/tauri-plugin-remote-push/1.0.10/tauri_plugin_remote_push/type

Introduces the `into_ok` method, an experimental nightly-only API for Rust's `Result`. This method retrieves the `Ok` value without panicking. It's designed as a compile-time safeguard, ensuring that the code will not compile if the `Result`'s error type can actually occur, thus promoting safer error handling practices.

```rust
fn only_good_news() -> Result<String, !> {
    Ok("this is fine".into())
}

let s: String = only_good_news().into_ok();
println!("{s}");
```

--------------------------------

### Rust: Using a Default Value with `unwrap_or`

Source: https://docs.rs/tauri-plugin-remote-push/1.0.10/tauri_plugin_remote_push/type

Shows how to use `unwrap_or` to get the `Ok` value from a `Result` or return a provided default value if the `Result` is `Err`. The default value is eagerly evaluated.

```rust
let default = 2;
let x: Result<u32, &str> = Ok(9);
assert_eq!(x.unwrap_or(default), 9);

let x: Result<u32, &str> = Err("error");
assert_eq!(x.unwrap_or(default), default);
```

--------------------------------

### Rust: Map Ok value in Result

Source: https://docs.rs/tauri-plugin-remote-push/1.0.10/tauri_plugin_remote_push/type

Details the `map` method for Rust's Result type. This method applies a function to the value inside an Ok variant, transforming it while leaving Err variants untouched. The example iterates through lines of text, parsing numbers and doubling them if successful.

```rust
let line = "1\n2\n3\n4\n";

for num in line.lines() {
    match num.parse::<i32>().map(|i| i * 2) {
        Ok(n) => println!("{n}"),
        Err(..) => {} 
    }
}
```

--------------------------------

### Rust: Map Ok value to U or default for Err

Source: https://docs.rs/tauri-plugin-remote-push/1.0.10/tauri_plugin_remote_push/type

Introduces the experimental `map_or_default` method for Rust's Result type. This nightly-only feature maps the Ok value using a function or returns the default value of type U if the Result is an Err. Examples show usage with both Ok and Err.

```rust
#![feature(result_option_map_or_default)]

let x: Result<_, &str> = Ok("foo");
let y: Result<&str, _> = Err("bar");

assert_eq!(x.map_or_default(|x| x.len()), 3);
assert_eq!(y.map_or_default(|y| y.len()), 0);
```

--------------------------------

### Rust: Get mutable reference to Result value

Source: https://docs.rs/tauri-plugin-remote-push/1.0.10/tauri_plugin_remote_push/type

Explains the `as_mut` method for Rust's Result type. This method converts a mutable reference to a Result (`&mut Result<T, E>`) into a Result of mutable references (`Result<&mut T, &mut E>`), allowing in-place modification. Examples demonstrate mutation for both Ok and Err variants.

```rust
fn mutate(r: &mut Result<i32, i32>) {
    match r.as_mut() {
        Ok(v) => *v = 42,
        Err(e) => *e = 0,
    }
}

let mut x: Result<i32, i32> = Ok(2);
mutate(&mut x);
assert_eq!(x.unwrap(), 42);

let mut x: Result<i32, i32> = Err(13);
mutate(&mut x);
assert_eq!(x.unwrap_err(), 0);
```

--------------------------------

### Rust: Unsafe Unwrapping of `Ok` Value

Source: https://docs.rs/tauri-plugin-remote-push/1.0.10/tauri_plugin_remote_push/type

Provides an example of `unwrap_unchecked`, an unsafe method that returns the contained `Ok` value without checking if the `Result` is `Err`. Calling this on an `Err` results in undefined behavior. This should only be used when the `Ok` state is guaranteed.

```rust
let x: Result<u32, &str> = Ok(2);
assert_eq!(unsafe { x.unwrap_unchecked() }, 2);
```

```rust
let x: Result<u32, &str> = Err("emergency failure");
unsafe { x.unwrap_unchecked() }; // Undefined behavior!
```

--------------------------------

### Rust: Map Result to value using fallback or mapping function

Source: https://docs.rs/tauri-plugin-remote-push/1.0.10/tauri_plugin_remote_push/type

Details the `map_or_else` method for Rust's Result type. This method applies a fallback function to the Err value or a mapping function to the Ok value, returning the result. The example demonstrates behavior for both Ok and Err variants.

```rust
let k = 21;

let x : Result<_, &str> = Ok("foo");
assert_eq!(x.map_or_else(|e| k * 2, |v| v.len()), 3);

let x : Result<&str, _> = Err("bar");
assert_eq!(x.map_or_else(|e| k * 2, |v| v.len()), 42);
```

--------------------------------

### Rust: Convert Result to Option (Err value)

Source: https://docs.rs/tauri-plugin-remote-push/1.0.10/tauri_plugin_remote_push/type

Demonstrates the `err` method for Rust's Result type. This method consumes the Result and returns an Option containing the error value if it's an Err variant, otherwise it returns None. Examples cover both Ok and Err scenarios.

```rust
let x: Result<u32, &str> = Ok(2);
assert_eq!(x.err(), None);

let x: Result<u32, &str> = Err("Nothing here");
assert_eq!(x.err(), Some("Nothing here"));
```

--------------------------------

### Rust: Map Result to value or default

Source: https://docs.rs/tauri-plugin-remote-push/1.0.10/tauri_plugin_remote_push/type

Explains the `map_or` method for Rust's Result type. This method returns the result of applying a function to the Ok value, or a provided default value if the Result is an Err. The example shows different outcomes based on whether the Result is Ok or Err.

```rust
let x: Result<_, &str> = Ok("foo");
assert_eq!(x.map_or(42, |v| v.len()), 3);

let x: Result<&str, _> = Err("bar");
assert_eq!(x.map_or(42, |v| v.len()), 42);
```

--------------------------------

### Rust: Safely Get Err Value (Nightly)

Source: https://docs.rs/tauri-plugin-remote-push/1.0.10/tauri_plugin_remote_push/type

Presents the `into_err` method, an experimental nightly-only API for Rust's `Result`. This method extracts the `Err` value without panicking. Similar to `into_ok`, it acts as a compile-time check, failing compilation if the `Ok` type can genuinely occur, thereby enhancing code safety.

```rust
fn only_bad_news() -> Result<!, String> {
    Err("Oops, it failed".into())
}

let error: String = only_bad_news().into_err();
println!("{error}");
```

--------------------------------

### Initialize tauri-plugin-remote-push

Source: https://docs.rs/tauri-plugin-remote-push/1.0.10/src/tauri_plugin_remote_push/lib

Initializes the tauri-plugin-remote-push plugin. It sets up the invoke handler for commands like 'get_token' and 'request_permission', and manages the plugin's state. This function is conditional based on the target platform (desktop or mobile).

```rust
use tauri::{
  plugin::{Builder, TauriPlugin},
  Manager,
  Runtime,
};

pub use models::*;

#[cfg(desktop)]
mod desktop;
#[cfg(mobile)]
mod mobile;

mod commands;
mod error;
mod models;

pub use error::{Error, Result};

#[cfg(desktop)]
use desktop::RemotePush;
#[cfg(mobile)]
use mobile::RemotePush;

/// Extensions to [`tauri::App`], [`tauri::AppHandle`] and [`tauri::Window`] to access the remote-push APIs.
pub trait RemotePushExt<R: Runtime> {
  fn remote_push(&self) -> &RemotePush<R>;
}

impl<R: Runtime, T: Manager<R>> crate::RemotePushExt<R> for T {
  fn remote_push(&self) -> &RemotePush<R> {
    self.state::<RemotePush<R>>().inner()
  }
}

/// Initializes the plugin.
pub fn init<R: Runtime>() -> TauriPlugin<R, Option<Config>> {
  Builder::<R, Option<Config>>::new("remote-push")
    .invoke_handler(tauri::generate_handler![
      commands::get_token,
      commands::request_permission
    ])
    .setup(|app, api| {
      let config = api.config().clone();
      #[cfg(mobile)]
      let remote_push = mobile::init(app, api, config)?;
      #[cfg(desktop)]
      let remote_push = desktop::init(app, api, config)?;
      app.manage(remote_push);
      Ok(())
    })
    .build()
}
```

--------------------------------

### Initialize RemotePush Plugin in Rust

Source: https://docs.rs/tauri-plugin-remote-push/1.0.10/src/tauri_plugin_remote_push/desktop

This Rust code initializes the tauri-plugin-remote-push, providing access to its APIs. It requires a generic Runtime, a DeserializeOwned type for configuration, and an AppHandle. It returns a RemotePush struct which wraps the AppHandle.

```rust
use serde::de::DeserializeOwned;
use tauri::{plugin::PluginApi, AppHandle, Runtime};

use crate::models::*;

pub fn init<R: Runtime, C: DeserializeOwned>(
 app: &AppHandle<R>,
 _api: PluginApi<R, C>,
 _config: Option<Config>,
) -> crate::Result<RemotePush<R>> {
 Ok(RemotePush(app.clone()))
}

/// Access to the remote-push APIs.
pub struct RemotePush<R: Runtime>(AppHandle<R>);

impl<R: Runtime> RemotePush<R> {
 pub fn get_token(&self) -> crate::Result<String> {
 Ok("".to_string())
 }

 pub fn request_permission(&self) -> crate::Result<()> {
 Ok(())
 }
}
```

--------------------------------

### Rust: Providing Alternative `Ok` Values with `or`

Source: https://docs.rs/tauri-plugin-remote-push/1.0.10/tauri_plugin_remote_push/type

Illustrates the `or` method for `Result`. If the initial `Result` is `Ok`, its value is returned. If it's `Err`, the `Result` provided as an argument to `or` is returned. Note that arguments to `or` are eagerly evaluated.

```rust
let x: Result<u32, &str> = Ok(2);
let y: Result<u32, &str> = Err("late error");
assert_eq!(x.or(y), Ok(2));

let x: Result<u32, &str> = Err("early error");
let y: Result<u32, &str> = Ok(2);
assert_eq!(x.or(y), Ok(2));

let x: Result<u32, &str> = Err("not a 2");
let y: Result<u32, &str> = Err("late error");
assert_eq!(x.or(y), Err("late error"));

let x: Result<u32, &str> = Ok(2);
let y: Result<u32, &str> = Ok(100);
assert_eq!(x.or(y), Ok(2));
```

--------------------------------

### Define Configuration and Permission State Models (Rust)

Source: https://docs.rs/tauri-plugin-remote-push/1.0.10/src/tauri_plugin_remote_push/models

Defines the data structures for the remote push plugin configuration and permission state. These structures are used to serialize and deserialize data, with `Config` handling sender ID and `PermissionState` indicating permission grants. They rely on the `serde` crate for serialization.

```rust
use serde::{Deserialize, Serialize};

#[derive(Debug, Clone, serde::Deserialize)]
pub struct Config {
    #[serde(rename = "senderId")]
    pub sender_id: Option<String>,
}

#[derive(Debug, Clone, Default, Deserialize, Serialize)]
#[serde(rename_all = "camelCase")]
pub struct PermissionState {
    pub granted: bool,
}
```

--------------------------------

--------------------------------

### Rust: Implementing Try for Result<T, E> (Nightly)

Source: https://docs.rs/tauri-plugin-remote-push/1.0.10/tauri_plugin_remote_push/type

Experimental nightly feature that implements the Try trait for Result<T, E>. This enables advanced control flow with the `?` operator, defining `Output`, `Residual`, and methods like `branch` and `from_output`.

```rust
impl<T, E> Try for Result<T, E> {
    type Output = T;
    type Residual = Result<Infallible, E>;

    fn from_output(output: Self::Output) -> Self {
        Ok(output)
    }

    fn branch(self) -> ControlFlow<Self::Residual, Self::Output> {
        match self {
            Ok(v) => ControlFlow::Continue(v),
            Err(e) => ControlFlow::Break(Err(e)),
        }
    }
}
```

--------------------------------

### Rust: Implementing PartialEq for Result<T, E>

Source: https://docs.rs/tauri-plugin-remote-push/1.0.10/tauri_plugin_remote_push/type

    fn eq(&self, other: &Result<T, E>) -> bool {
        match (self, other) {
            (Ok(a), Ok(b)) => a == b,
            (Err(a), Err(b)) => a == b,
            _ => false,
        }
    }

    fn ne(&self, other: &Result<T, E>) -> bool {
        !self.eq(other)
    }
}
```

--------------------------------

### Result Methods

```

## `unwrap_unchecked`

### Description
Returns the contained `Ok` value, consuming the `self` value, without checking that the value is not an `Err`.

### Method
`unwrap_unchecked`

### Safety

```rust
let x: Result<u32, &str> = Ok(2);
unsafe { x.unwrap_err_unchecked() }; // Undefined behavior!

let x: Result<u32, &str> = Err("emergency failure");
assert_eq!(unsafe { x.unwrap_err_unchecked() }, "emergency failure");
```
```

--------------------------------

### Rust: Combine Results with 'and'

Source: https://docs.rs/tauri-plugin-remote-push/1.0.10/tauri_plugin_remote_push/type

Explains the `and` method for Rust's `Result`. If the initial `Result` is `Ok`, `and` returns the second `Result` provided as an argument. If the initial `Result` is `Err`, it returns that `Err` value. Note that arguments to `and` are evaluated immediately, unlike `and_then`.

```rust
let x: Result<u32, &str> = Ok(2);
let y: Result<&str, &str> = Err("late error");
assert_eq!(x.and(y), Err("late error"));

let x: Result<u32, &str> = Err("early error");
let y: Result<&str, &str> = Ok("foo");
assert_eq!(x.and(y), Err("early error"));

let x: Result<u32, &str> = Err("not a 2");
let y: Result<&str, &str> = Err("late error");
assert_eq!(x.and(y), Err("not a 2"));

let x: Result<u32, &str> = Ok(2);
let y: Result<&str, &str> = Ok("different result type");
assert_eq!(x.and(y), Ok("different result type"));
```

--------------------------------

### Rust: Cloning a Result

Source: https://docs.rs/tauri-plugin-remote-push/1.0.10/tauri_plugin_remote_push/type

Demonstrates the `Clone` trait implementation for `Result<T, E>`, where both `T` and `E` must also implement `Clone`. The `clone` method creates a duplicate of the `Result` value.

```rust
fn clone(&self) -> Result<T, E>
where T: Clone,
      E: Clone,
```

--------------------------------

### Rust: Implementing PartialOrd for Result<T, E>

Source: https://docs.rs/tauri-plugin-remote-push/1.0.10/tauri_plugin_remote_push/type

Enables partial ordering comparisons (<, <=, >, >=) for Result types. This requires that both the success type `T` and the error type `E` implement PartialOrd.

```rust
impl<T, E>
where T: PartialOrd,
      E: PartialOrd,
PartialOrd for Result<T, E> {
    fn partial_cmp(&self, other: &Result<T, E>) -> Option<Ordering> {
        match (self, other) {
            (Ok(a), Ok(b)) => a.partial_cmp(b),
            (Err(a), Err(b)) => a.partial_cmp(b),
            (Ok(_), Err(_)) => Some(Ordering::Greater), // Ok is considered greater than Err
            (Err(_), Ok(_)) => Some(Ordering::Less),    // Err is considered less than Ok
        }
    }

    // Default implementations for lt, le, gt, ge using partial_cmp
    fn lt(&self, other: &Self) -> bool {
        self.partial_cmp(other) == Some(Ordering::Less)
    }

    fn le(&self, other: &Self) -> bool {
        self.partial_cmp(other) != Some(Ordering::Greater)
    }

    fn gt(&self, other: &Self) -> bool {
        self.partial_cmp(other) == Some(Ordering::Greater)
    }

    fn ge(&self, other: &Self) -> bool {
        self.partial_cmp(other) != Some(Ordering::Less)
    }
}
```

### Rust: Calculating Product of Results

Source: https://docs.rs/tauri-plugin-remote-push/1.0.10/tauri_plugin_remote_push/type

Implements the Product trait for Result<T, E>, allowing the calculation of a product from an iterator of Result<U, E> types. If any element is an Err, it short-circuits and returns that Err. Otherwise, it returns the product of the Ok values.

```rust
impl<T, U, E>
where T: Product<U>,
Product<Result<U, E>> for Result<T, E> {
    fn product<I>(iter: I) -> Result<T, E>
    where I: Iterator<Item = Result<U, E>> {
        let mut result = None;
        for item in iter {
            match item {
                Ok(val) => {
                    result = match result {
                        Some(acc) => Some(acc.checked_mul(val)?), // Assuming T has checked_mul for safety
                        None => Some(val),
                    };
                }
                Err(e) => return Err(e),
            }
        }
        Ok(result.unwrap_or_else(T::one)) // Assuming T has a `one` method for the identity element
    }
}
```

--------------------------------

### Rust: Debugging a Result

```rust
impl<T, E> Debug for Result<T, E>
where T: Debug,
      E: Debug,
```

--------------------------------

### Result::expect

### Rust: Checking if Result is Ok and matches predicate

Source: https://docs.rs/tauri-plugin-remote-push/1.0.10/tauri_plugin_remote_push/type

The `is_ok_and` method checks if the `Result` is `Ok` and if the contained value satisfies a given predicate function. It returns `true` only if both conditions are met.

```rust
let x: Result<u32, &str> = Ok(2);
assert_eq!(x.is_ok_and(|x| x > 1), true);

let x: Result<u32, &str> = Ok(0);
assert_eq!(x.is_ok_and(|x| x > 1), false);

let x: Result<u32, &str> = Err("hey");
assert_eq!(x.is_ok_and(|x| x > 1), false);
```

```rust
let x: Result<String, &str> = Ok("ownership".to_string());
assert_eq!(x.as_ref().is_ok_and(|x| x.len() > 1), true);
println!("still alive {:?}", x);
```

--------------------------------

### TryWriteable Trait Methods in Rust

Source: https://docs.rs/tauri-plugin-remote-push/1.0.10/tauri_plugin_remote_push/type

This snippet showcases methods from the `TryWriteable` trait. These methods facilitate writing data to various sinks, such as generic `Write` implementors, sinks supporting parts (annotations), or directly to a `String`. Error handling is managed through Rust's `Result` type.

```rust
fn try_write_to<W>(&self, sink: &mut W) -> Result<Result<(), <Result<T, E> as TryWriteable>::Error>, Error>
where
    W: Write + ?Sized,
```

```rust
fn try_write_to_parts<S>(&self, sink: &mut S) -> Result<Result<(), <Result<T, E> as TryWriteable>::Error>, Error>
where
    S: PartsWrite + ?Sized,
```

```rust
fn try_write_to_string(&self) -> Result<Cow<'_, str>, (<Result<T, E> as TryWriteable>::Error, Cow<'_, str>)>
```

```rust
fn writeable_length_hint(&self) -> LengthHint
```

--------------------------------

### Rust: Adding Context to Errors

Source: https://docs.rs/tauri-plugin-remote-push/1.0.10/tauri_plugin_remote_push/type

Illustrates the `Context` trait for `Result<T, E>`, where `E` must implement `StdError`. The `context` method wraps an error with additional displayable context. The `with_context` method provides lazily evaluated context.

```rust
fn context<C>(self, context: C) -> Result<T, Error>
where C: Display + Send + Sync + 'static,

fn with_context<C, F>(self, context: F) -> Result<T, Error>
where C: Display + Send + Sync + 'static,
      F: FnOnce() -> C,
```

--------------------------------

### Implementations for Result<T, E> in Rust

Source: https://docs.rs/tauri-plugin-remote-push/1.0.10/tauri_plugin_remote_push/type

This section details various trait implementations for the standard Rust `Result` type. These include `Copy`, `Eq`, `StructuralPartialEq`, and `UseCloned`, provided that the generic types `T` and `E` also implement the respective traits. These implementations enable common operations and comparisons on `Result` values.

```rust
impl<T, E> Copy for Result<T, E>
where
    T: Copy,
    E: Copy,
```

```rust
impl<T, E> Eq for Result<T, E>
where
    T: Eq,
    E: Eq,
```

```rust
impl<T, E> StructuralPartialEq for Result<T, E>
```

```rust
impl<T, E> UseCloned for Result<T, E>
where
    T: UseCloned,
    E: UseCloned,
```

--------------------------------

```

--------------------------------

### Rust: Chain Operations with 'and_then'

Source: https://docs.rs/tauri-plugin-remote-push/1.0.10/tauri_plugin_remote_push/type

Describes the `and_then` method for Rust's `Result`. If the `Result` is `Ok`, it calls the provided closure `op` with the contained value and returns the `Result` produced by the closure. If the `Result` is `Err`, it returns that `Err` value directly. This method is ideal for sequential operations where each step might fail.

```rust
let x: Result<u32, &str> = Ok(2);
let result = x.and_then(|v| {
    if v == 2 {
        Ok("two")
    } else {
        Err("not two")
    }
});
assert_eq!(result, Ok("two"));

let x: Result<u32, &str> = Err("an error");
let result = x.and_then(|v| {
    if v == 2 {
        Ok("two")
    } else {
        Err("not two")
    }
});
assert_eq!(result, Err("an error"));
```

--------------------------------

### Rust: Checking if Result is Ok

Source: https://docs.rs/tauri-plugin-remote-push/1.0.10/tauri_plugin_remote_push/type

The `is_ok` method returns `true` if the `Result` instance is the `Ok` variant and `false` otherwise. This is a common way to check for success without unwrapping the value.

```rust
let x: Result<i32, &str> = Ok(-3);
assert_eq!(x.is_ok(), true);

let x: Result<i32, &str> = Err("Some error message");
assert_eq!(x.is_ok(), false);
```

--------------------------------

### Result::inspect

Source: https://docs.rs/tauri-plugin-remote-push/1.0.10/tauri_plugin_remote_push/type

Calls a closure with a reference to the contained value if `Ok` and returns the original result.

```APIDOC
## POST /result/inspect

### Description

### Method
POST

### Endpoint
/result/inspect

### Parameters

{
  "result": {
    "Ok_value": 4
  }
}
```
```

### Convert Result<&T, &E> in Rust

Source: https://docs.rs/tauri-plugin-remote-push/1.0.10/tauri_plugin_remote_push/type

The `as_deref` method converts a `Result<T, E>` or `&Result<T, E>` into a `Result<&<T as Deref>::Target, &E>` by coercing the `Ok` variant via `Deref`. This allows accessing the underlying data through a reference without consuming the original Result.

```rust
let x: Result<String, u32> = Ok("hello".to_string());
let y: Result<&str, &u32> = Ok("hello");
assert_eq!(x.as_deref(), y);

let x: Result<String, u32> = Err(42);
let y: Result<&str, &u32> = Err(&42);
assert_eq!(x.as_deref(), y);
```

--------------------------------

### Rust: Unwrap Result Value or Panic

Source: https://docs.rs/tauri-plugin-remote-push/1.0.10/tauri_plugin_remote_push/type

Demonstrates the `unwrap` method on Rust's `Result` type. It returns the contained `Ok` value, but panics if the value is an `Err`, using the `Err`'s value as the panic message. This is useful for cases where an `Err` is considered an unrecoverable program error.

```rust
let x: Result<u32, &str> = Ok(2);
assert_eq!(x.unwrap(), 2);
```

```rust
let x: Result<u32, &str> = Err("emergency failure");
x.unwrap(); // panics with `emergency failure`
```

--------------------------------

### Rust: Chaining Fallible Operations with `and_then`

Source: https://docs.rs/tauri-plugin-remote-push/1.0.10/tauri_plugin_remote_push/type

Demonstrates chaining fallible operations that return `Result`. The `and_then` method is used to apply a function to the `Ok` value, propagating `Err` values directly. This is useful for sequential operations where any failure should stop the chain. It handles potential overflows during multiplication.

```rust
fn sq_then_to_string(x: u32) -> Result<String, &'static str> {
    x.checked_mul(x).map(|sq| sq.to_string()).ok_or("overflowed")
}

assert_eq!(Ok(2).and_then(sq_then_to_string), Ok(4.to_string()));
assert_eq!(Ok(1_000_000).and_then(sq_then_to_string), Err("overflowed"));
assert_eq!(Err("not a number").and_then(sq_then_to_string), Err("not a number"));
```

--------------------------------

### Rust: Collect Results into a single Result using `FromIterator`

Source: https://docs.rs/tauri-plugin-remote-push/1.0.10/tauri_plugin_remote_push/type

Demonstrates how to use `FromIterator` to collect an iterator of `Result` types into a single `Result`. If any element in the iterator is an `Err`, the collection stops and that `Err` is returned. Otherwise, a container with all the `Ok` values is returned. This is useful for batch operations where failure of one item should halt the entire process.

```Rust
let v = vec![1, 2];
let res: Result<Vec<u32>, &'static str> = v.iter().map(|x: &u32| 
    x.checked_add(1).ok_or("Overflow!")
).collect();
assert_eq!(res, Ok(vec![2, 3]));
```

```Rust
let v = vec![1, 2, 0];
let res: Result<Vec<u32>, &'static str> = v.iter().map(|x: &u32| 
    x.checked_sub(1).ok_or("Underflow!")
).collect();
assert_eq!(res, Err("Underflow!"));
```

```Rust
let v = vec![3, 2, 1, 10];
let mut shared = 0;
let res: Result<Vec<u32>, &'static str> = v.iter().map(|x: &u32| {
    shared += x;
    x.checked_sub(2).ok_or("Underflow!")
}).collect();
assert_eq!(res, Err("Underflow!"));
assert_eq!(shared, 6);
```

--------------------------------

### Unwrap Ok Value in Rust Result

Source: https://docs.rs/tauri-plugin-remote-push/1.0.10/tauri_plugin_remote_push/type

The `unwrap` method returns the contained `Ok` value, consuming the `self` value. If the `Result` is `Err`, it panics. This method is discouraged due to its potential to cause program termination. Prefer pattern matching or other methods like `unwrap_or`.

```rust
let x: Result<u32, u32> = Ok(2);
assert_eq!(x.unwrap(), 2);
```

--------------------------------

### Rust: Lazy Error Handling with `or_else`

Source: https://docs.rs/tauri-plugin-remote-push/1.0.10/tauri_plugin_remote_push/type

Demonstrates the `or_else` method for `Result`. If the initial `Result` is `Ok`, its value is returned. If it's `Err`, a closure is called with the error value, and the `Result` returned by the closure is used. This allows for lazy evaluation of the alternative error handling.

```rust
fn sq(x: u32) -> Result<u32, u32> { Ok(x * x) }
fn err(x: u32) -> Result<u32, u32> { Err(x) }

assert_eq!(Ok(2).or_else(sq).or_else(sq), Ok(2));
assert_eq!(Ok(2).or_else(err).or_else(sq), Ok(2));
assert_eq!(Err(3).or_else(sq).or_else(err), Ok(9));
assert_eq!(Err(3).or_else(err).or_else(err), Err(3));
```
