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

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;
  }
}
