Struct JsNull

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

The type of JavaScript null primitives.

Example

let null = cx.null();
cx.global::<JsObject>("console")?
    .method(&mut cx, "log")?
    .arg(null)?
    .exec()?;

Implementations

impl JsNull

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