Struct boa_engine::object::ObjectInitializer
source · pub struct ObjectInitializer<'ctx> { /* private fields */ }
Expand description
Builder for creating objects with properties.
§Examples
let mut context = Context::default();
let object = ObjectInitializer::new(&mut context)
.property(js_string!("hello"), js_string!("world"), Attribute::all())
.property(1, 1, Attribute::all())
.function(
NativeFunction::from_fn_ptr(|_, _, _| Ok(JsValue::undefined())),
js_string!("func"),
0,
)
.build();
The equivalent in JavaScript would be:
let object = {
hello: "world",
"1": 1,
func: function() {}
}
