Enum stdweb::Value

pub enum Value {
    Undefined,
    Null,
    Bool(bool),
    Number(Number),
    String(String),
    Array(Array),
    Object(Object),
    Reference(Reference),
}

A type representing a JavaScript value.

This type implements a rich set of conversions from and into standard Rust types, for example:

let v1: Value = "Hello world!".into();
let v2: Value = true.into();
let v3: Value = vec![ 1, 2, 3 ].into();
let v4: Value = Null.into();
let v5: Value = 123_u64.try_into().unwrap();

let v1_r: String = v1.try_into().unwrap();
let v2_r: bool = v2.try_into().unwrap();
let v3_r: Vec< i32 > = v3.try_into().unwrap();
let v4_r: Option< String > = v4.try_into().unwrap(); // Will be `None`.
let v5_r: u64 = v5.try_into().unwrap();

Methods

impl Value

fn is_reference(&self) -> bool

Checks whenever the Value is of the Reference variant.

fn is_object(&self) -> bool

Checks whenever the Value is of the Object variant.

fn is_array(&self) -> bool

Checks whenever the Value is of the Array variant.

fn as_reference(&self) -> Option<&Reference>

Gets a reference to the Reference inside this Value.

fn as_object(&self) -> Option<&Object>

Gets a reference to the Object inside this Value.

fn as_array(&self) -> Option<&Array>
