A trait for borrowed JSON values.

Required Associated Types

type Owned: Json<Borrowed<'a> = Self> + 'a

The type of owned JSON values.

type Array: ArrayRef<'a, JsonRef = Self>

The type of borrowed JSON arrays.

type Object: ObjectRef<'a, JsonRef = Self>

The type of borrowed JSON objects.

Required Methods

fn to_owned(self) -> Self::Owned

Creates an owned JSON value.

fn null() -> Self

Returns a null value.

fn as_bool(self) -> Option<bool>

If the JSON is a boolean, returns the associated bool. Returns None otherwise.

fn as_number(self) -> Option<Number>

If the JSON is a number, returns the associated number. Returns None otherwise.

fn as_str(self) -> Option<&'a str>

If the JSON is a string, returns the associated string. Returns None otherwise.

fn as_array(self) -> Option<Self::Array>

If the JSON is an array, returns the associated array. Returns None otherwise.

fn as_object(self) -> Option<Self::Object>

If the JSON is an object, returns the associated object. Returns None otherwise.

fn is_null(self) -> bool

Returns true if the value is null.

Provided Methods

fn is_bool(self) -> bool

Returns true if the value is a boolean.

fn is_number(self) -> bool

Returns true if the value is a number.

fn is_string(self) -> bool

Returns true if the value is a string.

fn is_array(self) -> bool

Returns true if the value is an array.

fn is_object(self) -> bool

Returns true if the value is an object.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
