### Rust Socket.IO Client Example Usage

Source: https://docs.rs/rust_socketio/latest/rust_socketio/index

Demonstrates how to use the rust_socketio crate to connect to a Socket.IO server, register event callbacks, emit messages, and handle acknowledgments. It utilizes ClientBuilder for configuration and serde_json for JSON payloads. The callback function handles received text or binary data and emits a confirmation message.

```rust
use rust_socketio::{ClientBuilder, Payload, RawClient};
use serde_json::json;
use std::time::Duration;

// define a callback which is called when a payload is received
// this callback gets the payload as well as an instance of the
// socket to communicate with the server
let callback = |payload: Payload, socket: RawClient| {
       match payload {
           Payload::Text(values) => println!("Received: {:#?}", values),
           Payload::Binary(bin_data) => println!("Received bytes: {:#?}", bin_data),
           // This variant is deprecated, use Payload::Text instead
           Payload::String(str) => println!("Received: {}", str)
       }
       socket.emit("test", json!({{"got ack": true}})).expect("Server unreachable")
};

// get a socket that is connected to the admin namespace
let mut socket = ClientBuilder::new("http://localhost:4200/")
     .namespace("/admin")
     .on("test", callback)
     .on("error", |err, _| eprintln!("Error: {:#?}", err))
     .connect()
     .expect("Connection failed");

// emit to the "foo" event
let json_payload = json!({{"token": 123}});

socket.emit("foo", json_payload).expect("Server unreachable");

// define a callback, that's executed when the ack got acked
let ack_callback = |message: Payload, _: RawClient| {
    println!("Yehaa! My ack got acked?");
    println!("Ack data: {:#?}", message);
};

let json_payload = json!({{"myAckData": 123}});

// emit with an ack
let ack = socket
    .emit_with_ack("test", json_payload, Duration::from_secs(2), ack_callback)
    .expect("Server unreachable");

```

### Async Socket.IO Client Example in Rust

Source: https://docs.rs/rust_socketio/latest/rust_socketio/index

This Rust code demonstrates the usage of the asynchronous Socket.IO client. It shows how to define callbacks for receiving messages, connect to a server, emit messages with and without acknowledgments, and handle disconnections. It utilizes the tokio runtime and futures_util crate for asynchronous operations.

```rust
use futures_util::FutureExt;
use rust_socketio::{
    asynchronous::{Client, ClientBuilder},
    Payload,
};
use serde_json::json;
use std::time::Duration;

#[tokio::main]
async fn main() {
    // define a callback which is called when a payload is received
    // this callback gets the payload as well as an instance of the
    // socket to communicate with the server
    let callback = |payload: Payload, socket: Client| {
        async move {
            match payload {
                Payload::Text(values) => println!("Received: {:#?}", values),
                Payload::Binary(bin_data) => println!("Received bytes: {:#?}", bin_data),
                // This is deprecated use Payload::Text instead
                Payload::String(str) => println!("Received: {}", str),
            }
            socket
                .emit("test", json!({"got ack": true}))
                .await
                .expect("Server unreachable");
        }
        .boxed()
    };

    // get a socket that is connected to the admin namespace
    let socket = ClientBuilder::new("http://localhost:4200/")
        .namespace("/admin")
        .on("test", callback)
        .on("error", |err, _| {
            async move { eprintln!("Error: {:#?}", err) }.boxed()
        })
        .connect()
        .await
        .expect("Connection failed");

    // emit to the "foo" event
    let json_payload = json!({"token": 123});
    socket
        .emit("foo", json_payload)
        .await
        .expect("Server unreachable");

    // define a callback, that's executed when the ack got acked
    let ack_callback = |message: Payload, _: Client| {
        async move {
            println!("Yehaa! My ack got acked?");
            println!("Ack data: {:#?}", message);
        }
        .boxed()
    };

    let json_payload = json!({"myAckData": 123});
    // emit with an ack
    socket
        .emit_with_ack("test", json_payload, Duration::from_secs(2), ack_callback)
        .await
        .expect("Server unreachable");

    socket.disconnect().await.expect("Disconnect failed");
}

```

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

### Rust: Disconnecting from Socket.IO Server

Source: https://docs.rs/rust_socketio/latest/rust_socketio/client/struct

Demonstrates how to gracefully disconnect a Socket.IO client from the server using the `disconnect` method. This sends a closing packet to the server, ensuring a clean shutdown of the connection. The example shows disconnection after emitting a message.

```rust
use rust_socketio::{ClientBuilder, Payload, RawClient};
use serde_json::json;

fn handle_test(payload: Payload, socket: RawClient) {
    println!("Received: {:#?}", payload);
    socket.emit("test", json!({"hello": true})).expect("Server unreachable");
}

let mut socket = ClientBuilder::new("http://localhost:4200/")
    .on("test", handle_test)
    .connect()
    .expect("connection failed");

let json_payload = json!({"token": 123});

socket.emit("foo", json_payload);

// disconnect from the server
socket.disconnect();


```

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

### Rust: Emitting with Acknowledgment (ACK) in Socket.IO

Source: https://docs.rs/rust_socketio/latest/rust_socketio/client/struct

Shows how to send a message to a Socket.IO server and wait for an acknowledgment within a specified timeout. The `emit_with_ack` method allows for a callback function to be executed when the server responds. This is useful for ensuring messages are processed correctly. The example includes a callback to handle the received acknowledgment.

```rust
use rust_socketio::{ClientBuilder, Payload, RawClient};
use serde_json::json;
use std::time::Duration;
use std::thread::sleep;

let mut socket = ClientBuilder::new("http://localhost:4200/")
    .on("foo", |payload: Payload, _| println!("Received: {:#?}", payload))
    .connect()
    .expect("connection failed");

let ack_callback = |message: Payload, socket: RawClient| {
    match message {
        Payload::Text(values) => println!("{:#?}", values),
        Payload::Binary(bytes) => println!("Received bytes: {:#?}", bytes),
        // This is deprecated, use Payload::Text instead.
        Payload::String(str) => println!("{}", str),
   }
};

let payload = json!({"token": 123});
socket.emit_with_ack("foo", payload, Duration::from_secs(2), ack_callback).unwrap();

sleep(Duration::from_secs(2));
```

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

### Rust: Building and Connecting a Socket.IO Client

Source: https://docs.rs/rust_socketio/latest/rust_socketio/client/struct

Demonstrates how to build a Socket.IO client using ClientBuilder, set up event handlers, and establish a connection to a server. It shows basic connection and event handling for 'test' events.

```rust
use rust_socketio::{ClientBuilder, RawClient, Payload};
use serde_json::json;

let mut socket = ClientBuilder::new("http://localhost:4200/")
    .on("test", |payload: Payload, socket: RawClient| {
        println!("Received: {:#?}", payload);
        socket.emit("test", json!({"hello": true})).expect("Server unreachable");
     })
    .connect()
    .expect("connection failed");

let json_payload = json!({"token": 123});

let result = socket.emit("foo", json_payload);

assert!(result.is_ok());
```

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

### Socket.IO Client Initialization and Configuration

Source: https://docs.rs/rust_socketio/latest/rust_socketio/asynchronous/index

The `Client` struct represents a Socket.IO client connection, initialized with a server address and an optional namespace. The `ClientBuilder` facilitates configuring connection parameters such as callbacks, namespaces, and metadata before establishing a connection. The `connect` method on the builder acts as the final build step.

```rust
/// A socket which handles communication with the server.
/// It’s initialized with a specific address as well as an optional namespace to connect to.
/// If `None` is given the client will connect to the default namespace "/".
struct Client {} 

/// A builder class for a `socket.io` socket.
/// This handles setting up the client and configuring the callback, the namespace and metadata of the socket.
/// If no namespace is specified, the default namespace `/` is taken.
/// The `connect` method acts the `build` method and returns a connected `Client`.
struct ClientBuilder {}
```

### Async Callback Macro for Socket.IO Client

Source: https://docs.rs/rust_socketio/latest/rust_socketio/asynchronous/index

The `async_any_callback` macro is used to wrap asynchronous callback functions for the Socket.IO client. It simplifies the integration of async Rust functions as event handlers. Ensure the wrapped function adheres to the expected signature for callbacks.

```rust
/// A macro to wrap an async callback function to be used in the client.
macro_rules! async_any_callback {
    ($callback:expr) => {
        // Implementation details would go here
        $callback
    };
}
```

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

### Enable Async Feature for Rust Socket.IO

Source: https://docs.rs/rust_socketio/latest/rust_socketio/index

This code snippet shows how to enable the asynchronous support for the rust_socketio library in your Cargo.toml file by adding the 'async' feature flag. This is a prerequisite for using the asynchronous client.

```toml
rust_socketio = { version = "^0.4.1", features = ["async"] }
```

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

### Rust: Nightly-Only API - clone_to_uninit

Source: https://docs.rs/rust_socketio/latest/rust_socketio/client/struct

This is an experimental, nightly-only API. The `clone_to_uninit` function performs copy-assignment from `self` to a raw pointer `dest`. Use with caution.

```rust
unsafe fn clone_to_uninit(&self, dest: *mut u8)
```

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

### Async Callback Macro for Socket.IO Client

Source: https://docs.rs/rust_socketio/latest/rust_socketio/asynchronous/index

The `async_callback` macro is designed to wrap asynchronous callback functions for the Socket.IO client. This allows developers to use modern async Rust patterns for handling events. The macro handles the necessary boilerplate for integrating these async functions.

```rust
/// A macro to wrap an async callback function to be used in the client.
macro_rules! async_callback {
    ($callback:expr) => {
        // Implementation details would go here
        $callback
    };
}
```

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

### Define Async Callback with async_callback! Macro

Source: https://docs.rs/rust_socketio/latest/rust_socketio/macro

The `async_callback!` macro is designed to wrap an asynchronous callback function, making it suitable for use with the rust_socketio client. It simplifies the integration of async handlers for specific events. This macro requires the `rust_socketio` crate and typically works within a Tokio runtime environment.

```rust
macro_rules! async_callback {
    ($f:expr) => { ... };
}
```

```rust
use rust_socketio::async_callback;
use rust_socketio::asynchronous::{Client, ClientBuilder};
use rust_socketio::{Event, Payload};

pub async fn callback(payload: Payload, client: Client) {}

#[tokio::main]
async fn main() {
    let socket = ClientBuilder::new("http://example.com")
            .on("message", async_callback!(callback))
            .connect()
            .await;
}
```

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

### Rust: PolicyExt - And Operator

Source: https://docs.rs/rust_socketio/latest/rust_socketio/client/struct

The `and` method from `PolicyExt` combines two policies. It creates a new policy that only succeeds if both the original policy (`self`) and the `other` policy return `Action::Follow`.

```rust
impl<T> PolicyExt for T
where
    T: ?Sized,
{
    fn and<P, B, E>(self, other: P) -> And<T, P>
    where
        T: Policy<B, E>,
        P: Policy<B, E>,
    {
        // ... implementation details ...
    }
}
```

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

### Rust Policy: Combine Policies with `and`

Source: https://docs.rs/rust_socketio/latest/rust_socketio/event/enum

Creates a new `Policy` that requires both `self` and `other` policies to return `Action::Follow`. This is useful for defining complex conditional logic in a declarative way. No external dependencies are required beyond the `Policy` trait itself.

```rust
fn and<P, B, E>(self, other: P) -> And<T, P>
where T: Policy<B, E>, P: Policy<B, E>
```

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

### Rust: Client Structure Definition

Source: https://docs.rs/rust_socketio/latest/rust_socketio/client/struct

Provides the basic structure definition for the `Client` in rust_socketio. It indicates that the client has private fields and does not expose them directly.

```rust
pub struct Client { /* private fields */ }
```

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

### Default Implementation for ReconnectSettings in Rust

Source: https://docs.rs/rust_socketio/latest/rust_socketio/asynchronous/struct

This snippet shows the implementation of the Default trait for ReconnectSettings. The `default()` function provides a default ReconnectSettings value, which can be useful for initializing settings without explicit configuration.

```rust
fn default() -> ReconnectSettings
```

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

### Socket.IO Reconnection Settings

Source: https://docs.rs/rust_socketio/latest/rust_socketio/asynchronous/index

The `ReconnectSettings` struct allows for configuring parameters related to automatic reconnection attempts to a Socket.IO server. These settings can be modified before initiating a reconnection sequence. This provides control over how the client attempts to re-establish its connection.

```rust
/// Settings that can be updated before reconnecting to a server
struct ReconnectSettings {}
```

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

### Rust Policy: Combine Policies with `or`

Source: https://docs.rs/rust_socketio/latest/rust_socketio/event/enum

Creates a new `Policy` that returns `Action::Follow` if either `self` or `other` policy returns `Action::Follow`. This allows for defining alternative paths or fallback mechanisms within policy definitions. It relies on the `Policy` trait.

```rust
fn or<P, B, E>(self, other: P) -> Or<T, P>
where T: Policy<B, E>, P: Policy<B, E>
```

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

### Define ReconnectSettings Struct in Rust

Source: https://docs.rs/rust_socketio/latest/rust_socketio/asynchronous/struct

This snippet shows the basic definition of the ReconnectSettings struct. It is used to configure settings before reconnecting to a Socket.IO server. The struct contains private fields and is intended to be configured using its associated methods.

```rust
pub struct ReconnectSettings { /* private fields */ }
```

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

### Async Callback Macro for rust_socketio Client

Source: https://docs.rs/rust_socketio/latest/rust_socketio/asynchronous/macro

The async_callback! macro is used to wrap asynchronous callback functions for event handling in the rust_socketio client. It simplifies the process of defining and registering event handlers. This requires the rust_socketio crate and a tokio runtime for asynchronous execution.

```rust
macro_rules! async_callback {
    ($f:expr) => { ... };
}

use rust_socketio::async_callback;
use rust_socketio::asynchronous::{Client, ClientBuilder};
use rust_socketio::{Event, Payload};

pub async fn callback(payload: Payload, client: Client) {}

#[tokio::main]
async fn main() {
    let socket = ClientBuilder::new("http://example.com")
            .on("message", async_callback!(callback))
            .connect()
            .await;
}
```

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

### Rust: PolicyExt - Or Operator

Source: https://docs.rs/rust_socketio/latest/rust_socketio/client/struct

The `or` method from `PolicyExt` combines two policies. It creates a new policy that succeeds if either the original policy (`self`) or the `other` policy returns `Action::Follow`.

```rust
impl<T> PolicyExt for T
where
    T: ?Sized,
{
    fn or<P, B, E>(self, other: P) -> Or<T, P>
    where
        T: Policy<B, E>,
        P: Policy<B, E>,
    {
        // ... implementation details ...
    }
}
```

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

### Rust Policy Combination Methods

Source: https://docs.rs/rust_socketio/latest/rust_socketio/error/enum

These methods combine existing policies to create new ones. They require the generic types to implement the `Policy` trait for a given set of bounds and errors. The `and` method creates a policy that only follows if both policies follow, while the `or` method creates a policy that follows if either policy follows.

```Rust
impl<T> PolicyExt for T
where
    T: ?Sized,
{
    fn and<P, B, E>(self, other: P) -> And<T, P>
    where
        T: Policy<B, E>,
        P: Policy<B, E>,
    {
        // ... implementation details ...
    }

    fn or<P, B, E>(self, other: P) -> Or<T, P>
    where
        T: Policy<B, E>,
        P: Policy<B, E>,
    {
        // ... implementation details ...
    }
}
```

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

### Rust String Conversion Methods

Source: https://docs.rs/rust_socketio/latest/rust_socketio/error/enum

Provides methods for converting values to strings. `ToString::to_string` converts a value implementing `Display` into a `String`. `ToStringFallible::try_to_string` offers a non-panicking alternative that returns a `Result` to handle potential allocation failures.

```Rust
impl<T> ToString for T
where
    T: Display + ?Sized,
{
    fn to_string(&self) -> String {
        // ... implementation details ...
    }
}

impl<T> ToStringFallible for T
where
    T: Display,
{
    fn try_to_string(&self) -> Result<String, TryReserveError> {
        // ... implementation details ...
    }
}
```

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

### Rust: Implement VZip<V> for T

Source: https://docs.rs/rust_socketio/latest/rust_socketio/client/struct

The `VZip` trait is used in conjunction with `MultiLane` to provide a `vzip` method. The exact functionality depends on the `MultiLane` implementation.

```rust
impl<V, T> VZip<V> for T
where
    V: MultiLane<T>,
{
    fn vzip(self) -> V {
        // ... implementation details ...
    }
}
```

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

### Rust: Implement Display for rust_socketio Error

Source: https://docs.rs/rust_socketio/latest/rust_socketio/error/enum

Provides a `Display` implementation for the `Error` enum, allowing errors to be formatted as strings for user-friendly output or logging. This is crucial for error reporting.

```rust
impl Display for Error {
    fn fmt(&self, __formatter: &mut Formatter<'_>) -> Result
}
```

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

### Rust: Implement From<T> for T

Source: https://docs.rs/rust_socketio/latest/rust_socketio/client/struct

This implementation allows a type `T` to be converted from itself. The `from` function simply returns the argument unchanged.

```rust
impl<T> From<T> for T {
    fn from(t: T) -> T {
        t
    }
}
```

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

### Convert Bytes to Payload - Rust

Source: https://docs.rs/rust_socketio/latest/rust_socketio/payload/enum

Demonstrates how to convert a slice of static bytes (`&'static [u8]`) into a `Payload::Binary` variant. This is useful for initializing payloads with raw byte data.

```rust
impl From<&'static [u8]> for Payload {
    fn from(val: &'static [u8]) -> Self {
        // Implementation details would go here, likely converting bytes to Bytes
    }
}
```

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

### Rust: Updating Reconnect URL for Socket.IO Client

Source: https://docs.rs/rust_socketio/latest/rust_socketio/client/struct

Shows how to update the reconnection URL for an existing Socket.IO client. The `set_reconnect_url` method allows dynamically changing the server address the client attempts to connect to upon disconnection, which is useful for scenarios like updating query parameters.

```rust
pub fn set_reconnect_url<T: Into<String>>( &self, address: T, ) -> Result<(), Error>
```

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

### Implement TryFrom and TryInto for Rust types

Source: https://docs.rs/rust_socketio/latest/rust_socketio/payload/enum

These traits facilitate fallible conversions between types. `TryFrom` attempts to convert one type into another, returning a `Result`. `TryInto` is the reciprocal, allowing a type to be converted into another type that implements `TryFrom`.

```rust
impl<T, U> TryFrom<U> for T
where U: Into<T>,
Source§
#### type Error = Infallible
