Struct script::dom::bindings::import::module::jsapi::ForOfIterator

#[repr(C)]
pub struct ForOfIterator {
    pub cx_: *mut JSContext,
    pub iterator: Rooted<*mut JSObject>,
    pub nextMethod: Rooted<Value>,
    pub index: u32,
}

A convenience class for imitating a JS for-of loop. Typical usage:

JS::ForOfIterator it(cx);
if (!it.init(iterable)) {
  return false;
}
JS::Rooted<JS::Value> val(cx);
while (true) {
  bool done;
  if (!it.next(&val, &done)) {
    return false;
  }
  if (done) {
    break;
  }
  if (!DoStuff(cx, val)) {
    return false;
  }
}

Fields

cx_: *mut JSContext

iterator: Rooted<*mut JSObject>

nextMethod: Rooted<Value>

index: u32
