Struct ObjectInitializer

Source
pub struct ObjectInitializer<'context> { /* private fields */ }
Expand description

Builder for creating objects with properties.

§Examples

let mut context = Context::new();
let object = ObjectInitializer::new(&mut context)
    .property(
        "hello",
        "world",
        Attribute::all()
    )
    .property(
        1,
        1,
        Attribute::all()
    )
    .function(|_, _, _| Ok(JsValue::undefined()), "func", 0)
    .build();

The equivalent in JavaScript would be:

let object = {
    hello: "world",
    "1": 1,
    func: function() {}
}
