Expand description

Trait to allow accessing data inside a Value

Associated Types

The target for nested lookups

The type for Objects

The array structure

The object structure

Required methods

Tries to represent the value as a bool

Tries to represent the value as an i64

Tries to represent the value as an u64

Tries to represent the value as a f64

Tries to represent the value as a &str

Tries to represent the value as an array and returns a refference to it

Tries to represent the value as an object and returns a refference to it

Provided methods

Gets a ref to a value based on a key, returns None if the current Value isn’t an Object or doesn’t contain the key it was asked for.

Checks if a Value contains a given key. This will return flase if Value isn’t an object

Gets a ref to a value based on n index, returns None if the current Value isn’t an Array or doesn’t contain the index it was asked for.

Tries to get an element of an object as a bool

Tries to represent the value as an i128

Tries to get an element of an object as a i128

Tries to get an element of an object as a i64

Tries to represent the value as an i32

Tries to get an element of an object as a i32

Tries to represent the value as an i16

Tries to get an element of an object as a i16

Tries to represent the value as an i8

Tries to get an element of an object as a i8

Tries to represent the value as an u128

Tries to get an element of an object as a u128

Tries to get an element of an object as a u64

Tries to represent the value as an usize

Tries to get an element of an object as a usize

Tries to represent the value as an u32

Tries to get an element of an object as a u32

Tries to represent the value as an u16

Tries to get an element of an object as a u16

Tries to represent the value as an u8

Tries to get an element of an object as a u8

Tries to get an element of an object as a f64

Casts the current value to a f64 if possible, this will turn integer values into floats.

Tries to represent the value as a f32

Tries to get an element of an object as a f32

Tries to represent the value as a Char

Tries to get an element of an object as a str

Tries to get an element of an object as a array

Tries to get an element of an object as a object
