Struct JsBoolean

pub struct JsBoolean(/* private fields */);

The type of JavaScript Boolean primitives.

Example

// The two Boolean values:
let t = cx.boolean(true);
let f = cx.boolean(false);

// Call console.log(true, false):
cx.global::<JsObject>("console")?.method(&mut cx, "log")?.args((t, f))?.exec()?;

Implementations

impl JsBoolean

pub fn new<'a, C: Context<'a>>(cx: &mut C, b: bool) -> Handle<'a, JsBoolean>

Creates a Boolean value with value b.

pub fn value<'a, C: Context<'a>>(&self, cx: &mut C) -> bool

Returns the value of this Boolean as a Rust bool.
