Enum JsValue 

pub enum JsValue {
    Undefined,
    Null,
    Boolean(bool),
    String(String),
    Symbol(SymbolData),
    Number(JsNumberType),
    Object(JsObjectType),
}

JavaScript value representation.

Represents all possible JavaScript values including primitives and objects. This is the primary value type used throughout the engine.

Examples

use just::runner::ds::value::{JsValue, JsNumberType};

let undefined = JsValue::Undefined;
let null = JsValue::Null;
let boolean = JsValue::Boolean(true);
let string = JsValue::String("hello".to_string());
let number = JsValue::Number(JsNumberType::Integer(42));

Variants

Undefined

The undefined value.

Null

The null value.

Boolean(bool)

A boolean value (true or false).

String(String)

A string value.

Symbol(SymbolData)

A symbol value (ES6 symbols).

Number(JsNumberType)

A numeric value (integer or float).

Object(JsObjectType)

An object value (including arrays, functions, etc.).

Trait Implementations

impl Clone for JsValue

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for JsValue

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for JsValue

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for JsValue

fn eq(&self, other: &Self) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
