Source: https://docs.rs/tinyjson/2.5.1/tinyjson/trait.InnerAsRefMut.html

Examples of how the trait is implemented for various types including primitives, strings, and collections.

```rust
fn json_value_as_mut(v: &mut JsonValue) -> Option<&mut bool>
```

```rust
fn json_value_as_mut(v: &mut JsonValue) -> Option<&mut f64>
```

```rust
fn json_value_as_mut(v: &mut JsonValue) -> Option<&mut String>
```

```rust
fn json_value_as_mut(v: &mut JsonValue) -> Option<&mut Vec<JsonValue>>
```

```rust
fn json_value_as_mut( v: &mut JsonValue, ) -> Option<&mut HashMap<String, JsonValue>>
```

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

### InnerAsRef Implementations

Source: https://docs.rs/tinyjson/2.5.1/tinyjson/trait.InnerAsRef.html

Examples of implementing InnerAsRef for various standard types to allow safe access to JsonValue contents.

```rust
impl InnerAsRef for bool
fn json_value_as(v: &JsonValue) -> Option<&bool>
```

```rust
impl InnerAsRef for f64
fn json_value_as(v: &JsonValue) -> Option<&f64>
```

```rust
impl InnerAsRef for ()
fn json_value_as(v: &JsonValue) -> Option<&()>
```

```rust
impl InnerAsRef for String
fn json_value_as(v: &JsonValue) -> Option<&String>
```

```rust
impl InnerAsRef for Vec<JsonValue>
fn json_value_as(v: &JsonValue) -> Option<&Vec<JsonValue>>
```

```rust
impl InnerAsRef for HashMap<String, JsonValue>
fn json_value_as(v: &JsonValue) -> Option<&HashMap<String, JsonValue>>
```

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

### Retrieve inner value reference

Source: https://docs.rs/tinyjson/2.5.1/tinyjson/enum.JsonValue.html

Use get to access an immutable reference to the inner value, returning None if the type does not match.

```rust
use tinyjson::JsonValue;

let value: JsonValue = "[1, 2, 3]".parse().unwrap();
let vec: &Vec<_> = value.get().unwrap();
assert_eq!(vec[0], JsonValue::from(1.0));

// Try to convert with incorrect type
assert!(value.get::<f64>().is_none());
```

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

### Configuring indentation

Source: https://docs.rs/tinyjson/2.5.1/tinyjson/struct.JsonGenerator.html

Shows how to set an indentation string for formatted JSON output.

```rust
use tinyjson::{JsonGenerator, JsonValue};

let v = JsonValue::from(vec![1.0.into(), 2.0.into(), 3.0.into()]);
let mut buf = vec![];
let mut gen = JsonGenerator::new(&mut buf).indent("        ");
gen.generate(&v).unwrap();

assert_eq!(String::from_utf8(buf).unwrap(),
"[
        1,
        2,
        3
]");
```

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

### Comparing formatted and unformatted output

Source: https://docs.rs/tinyjson/2.5.1/tinyjson/struct.JsonGenerator.html

Illustrates the difference between default serialization and serialization with a specified indent.

```rust
use tinyjson::{JsonGenerator, JsonValue};

let v = JsonValue::from(vec![1.0.into(), 2.0.into(), 3.0.into()]);

let mut buf = vec![];
let mut gen = JsonGenerator::new(&mut buf);
gen.generate(&v).unwrap();
assert_eq!(String::from_utf8(buf).unwrap(), "[1,2,3]");

let mut buf = vec![];
let mut gen = JsonGenerator::new(&mut buf).indent("  "); // with 2-spaces indent
gen.generate(&v).unwrap();

assert_eq!(String::from_utf8(buf).unwrap(),
"[
  1,
  2,
  3
]");
```

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

### Into Ok value

Source: https://docs.rs/tinyjson/2.5.1/tinyjson/type.JsonGenerateResult.html

Use into_ok to retrieve the Ok value without risk of panicking, typically used with infallible results.

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

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

### Basic JsonGenerator usage

Source: https://docs.rs/tinyjson/2.5.1/tinyjson/struct.JsonGenerator.html

Demonstrates serializing a simple string value into a buffer.

```rust
use tinyjson::{JsonGenerator, JsonValue};

let v = JsonValue::from("hello, world".to_string());
let mut buf = vec![];
let mut gen = JsonGenerator::new(&mut buf);
gen.generate(&v).unwrap();

assert_eq!(String::from_utf8(buf).unwrap(), "\"hello, world\"");
```

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

### JsonValue Usage and Conversion

Source: https://docs.rs/tinyjson/2.5.1/tinyjson/enum.JsonValue.html

Demonstrates creating a JsonValue, accessing inner data, checking types, and converting back to raw types.

```rust
use tinyjson::JsonValue;
use std::convert::TryInto;

// Convert from raw values using `From` trait
let value = JsonValue::from("this is string".to_string());

// Get reference to inner value
let maybe_number: Option<&f64> = value.get();
assert!(maybe_number.is_none());
let maybe_string: Option<&String> = value.get();
assert!(maybe_string.is_some());

// Check type of JSON value
assert!(matches!(value, JsonValue::String(_)));
assert!(value.is_string());

// Convert into raw values using `TryInto` trait
let original_value: String = value.try_into().unwrap();
```

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

### Parse JSON using JsonParser and FromStr

Source: https://docs.rs/tinyjson/2.5.1/tinyjson/struct.JsonParser.html

Demonstrates manual parsing using the JsonParser struct versus the more idiomatic FromStr implementation.

```rust
use tinyjson::{JsonParser, JsonValue};

let mut parser = JsonParser::new("[1, 2, 3]".chars());
let array = parser.parse().unwrap();

// Equivalent to the above code using `FromStr`
let array: JsonValue = "[1, 2, 3]".parse().unwrap();
```

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

### Fallback with or

Source: https://docs.rs/tinyjson/2.5.1/tinyjson/type.JsonGenerateResult.html

Returns the provided result if the current result is Err, otherwise returns the Ok value.

```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));
```

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

### Convert Result to reference

Source: https://docs.rs/tinyjson/2.5.1/tinyjson/type.JsonGenerateResult.html

Create a new Result containing references to the original values.

```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"));
```

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

### JsonParser::new

Source: https://docs.rs/tinyjson/2.5.1/tinyjson/struct.JsonParser.html

Creates a new instance of the JsonParser from an iterator of characters.

```APIDOC
## pub fn new(it: I) -> Self

### Description
Creates a new parser instance from an iterator which iterates characters. The iterator is usually built from `str::chars` for parsing `str` or `String` values.

### Parameters
- **it** (I: Iterator<Item = char>) - Required - The iterator providing characters to parse.
```

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

### Parse and Generate JSON with tinyjson

Source: https://docs.rs/tinyjson

Demonstrates parsing a JSON string into a JsonValue, accessing inner data, generating JSON strings, and manipulating values using standard containers.

```rust
use tinyjson::JsonValue;
use std::collections::HashMap;
use std::convert::TryInto;

let s = r#"
    {
        "bool": true,
        "arr": [1, null, "test"],
        "nested": {
            "blah": false,
            "blahblah": 3.14
        },
        "unicode": "\u2764"
    }
"#;

// Parse from strings
let parsed: JsonValue = s.parse().unwrap();

// Access to inner value represented with standard containers
let object: &HashMap<_, _> = parsed.get().unwrap();
println!("Parsed HashMap: {:?}", object);

// Generate JSON string
println!("{}", parsed.stringify().unwrap());
// Generate formatted JSON string with indent
println!("{}", parsed.format().unwrap());

// Convert to inner value represented with standard containers
let object: HashMap<_, _> = parsed.try_into().unwrap();
println!("Converted into HashMap: {:?}", object);

// Create JSON values from standard containers
let mut m = HashMap::new();
m.insert("foo".to_string(), true.into());
let mut v = JsonValue::from(m);

// Access with `Index` and `IndexMut` operators quickly
println!("{:?}", v["foo"]);
v["foo"] = JsonValue::from("hello".to_string());
println!("{:?}", v["foo"]);
```

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

### Convert Result to Option (Ok)

Source: https://docs.rs/tinyjson/2.5.1/tinyjson/type.JsonGenerateResult.html

Extract the success value into an Option.

```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);
```

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

### Expect a Result value

Source: https://docs.rs/tinyjson/2.5.1/tinyjson/type.JsonGenerateResult.html

Use expect to retrieve the Ok value or panic with a custom message if the result is Err.

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

```rust
let path = std::env::var("IMPORTANT_PATH")
    .expect("env variable `IMPORTANT_PATH` should be set by `wrapper_script.sh`");
```

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

### Chaining Results with and

Source: https://docs.rs/tinyjson/2.5.1/tinyjson/type.JsonGenerateResult.html

Returns the second result if the first is Ok, otherwise returns the Err value of the first.

```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"));
```

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

### Unwrap with default value

Returns the contained Ok value or a provided default value.

```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);
```

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

### Unwrap a Result value

Source: https://docs.rs/tinyjson/2.5.1/tinyjson/type.JsonGenerateResult.html

Use unwrap to retrieve the Ok value, panicking if the result is Err.

```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`
```

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

### TryFrom<JsonValue> for f64

Source: https://docs.rs/tinyjson/2.5.1/tinyjson/enum.JsonValue.html

Attempts to convert a JsonValue into a 64-bit float. Returns an UnexpectedValue error if the underlying type is not a number.

```APIDOC
## fn try_from(v: JsonValue) -> Result<f64, UnexpectedValue>

### Description
Converts a JsonValue into a 64-bit float. If the JsonValue does not contain a number, an UnexpectedValue error is returned.

### Parameters
- **v** (JsonValue) - The value to convert.

### Returns
- **Result<f64, UnexpectedValue>** - The converted float or an error if the type is incompatible.
```

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

### Using map_or_default on Result

Source: https://docs.rs/tinyjson/2.5.1/tinyjson/type.JsonGenerateResult.html

Maps Ok to a value or returns the default for the type if Err. Requires the nightly-only feature result_option_map_or_default.

```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);
```

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

### Index JsonValue with string keys

Source: https://docs.rs/tinyjson/2.5.1/tinyjson/enum.JsonValue.html

```rust
use tinyjson::JsonValue;
use std::collections::HashMap;

let mut m = HashMap::new();
m.insert("foo".to_string(), 1.0.into());
let v = JsonValue::from(m);
let i = &v["foo"];
assert_eq!(i, &JsonValue::Number(1.0));
```

```rust
let v = JsonValue::from(vec![]);
let _ = &v["foo"]; // Panic
```

```rust
let v = JsonValue::from(HashMap::new());
let _ = &v["foo"]; // Panic
```

```rust
let mut json: JsonValue = r#"
{
  "foo": {
    "bar": [
      { "target": 42 }
    ]
  }
}
"#.parse().unwrap();

// Access with index operator
let target_value: f64 = *json["foo"]["bar"][0]["target"].get().unwrap();
assert_eq!(target_value, 42.0);
```

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

### Unwrap with closure

Source: https://docs.rs/tinyjson/2.5.1/tinyjson/type.JsonGenerateResult.html

Returns the contained Ok value or computes it from a closure.

```rust
fn count(x: &str) -> usize { x.len() }
```

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

### Expect an error

Source: https://docs.rs/tinyjson/2.5.1/tinyjson/type.JsonGenerateResult.html

Use expect_err to retrieve the Err value, panicking if the result is Ok.

let x: Result<u32, &str> = Ok(10);
x.expect_err("Testing expect_err"); // panics with `Testing expect_err: 10`
```

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

### Detecting a JsonParseError

Source: https://docs.rs/tinyjson/2.5.1/tinyjson/struct.JsonParseError.html

Demonstrates how to catch and verify a parsing error when processing malformed JSON input.

```rust
use tinyjson::{JsonParser, JsonParseError};
let error = JsonParser::new("[1, 2, 3".chars()).parse().unwrap_err();
assert!(matches!(error, JsonParseError{..}));
```

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

### Using inspect on Result

Source: https://docs.rs/tinyjson/2.5.1/tinyjson/type.JsonGenerateResult.html

Executes a function with a reference to the Ok value without modifying the result.

```rust
let x: u8 = "4"
    .parse::<u8>()
    .inspect(|x| println!("original: {x}"))
    .map(|x| x.pow(3))
    .expect("failed to parse number");
```

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

### Check if Result is Ok with predicate

Source: https://docs.rs/tinyjson/2.5.1/tinyjson/type.JsonGenerateResult.html

Verify if a result is Ok and matches a specific condition.

```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);

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);
```

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

### Collect Result Iterator

Source: https://docs.rs/tinyjson/2.5.1/tinyjson/type.JsonGenerateResult.html

```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);
```

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

### Check if Result is Ok

Source: https://docs.rs/tinyjson/2.5.1/tinyjson/type.JsonGenerateResult.html

Verify if a result contains a success value.

  1,
  true,
  \"str\"
]");
```

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

### Unwrap an error

Source: https://docs.rs/tinyjson/2.5.1/tinyjson/type.JsonGenerateResult.html

Use unwrap_err to retrieve the Err value, panicking if the result is Ok.

```rust
let x: Result<u32, &str> = Ok(2);
x.unwrap_err(); // panics with `2`
```

```

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

### TryFrom Conversions for JsonValue

Source: https://docs.rs/tinyjson/2.5.1/tinyjson/enum.JsonValue.html

Convert JsonValue instances into native Rust types. These operations return an UnexpectedValue error if the underlying JSON type does not match the target type.

```rust
use tinyjson::JsonValue;
use std::convert::TryFrom;

let v = JsonValue::from(());
let r = <()>::try_from(v);
assert!(r.is_ok());

let v = JsonValue::from(1.0);
let r = <()>::try_from(v);
assert!(r.is_err());
```

```rust
use tinyjson::JsonValue;
use std::convert::TryFrom;
use std::collections::HashMap;

let mut m = HashMap::new();
m.insert("foo".to_string(), 42.0.into());
let v = JsonValue::from(m);
let r = <HashMap<_, _>>::try_from(v);
assert!(r.is_ok());

let v = JsonValue::from(1.0);
let r = <HashMap<_, _>>::try_from(v);
assert!(r.is_err());
```

```rust
use tinyjson::JsonValue;
