Struct 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

Implementations

impl ForOfIterator

pub unsafe fn init( &mut self, iterable: Handle<Value>, non_iterable_behavior: ForOfIterator_NonIterableBehavior, ) -> bool

pub unsafe fn next( &mut self, val: MutableHandle<Value>, done: *mut bool, ) -> bool

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
