A trait to get a reference to the underlying handle of an object.

Required Methods

Get a reference to the handle. One important use of such a reference is for object_wait_many.

Provided Methods

Interpret the reference as a raw handle (an integer type). Two distinct handles will have different raw values (so it can perhaps be used as a key in a data structure).

Set and clear userspace-accessible signal bits on an object. Wraps the zx_object_signal syscall.

Waits on a handle. Wraps the zx_object_wait_one syscall.

Causes packet delivery on the given port when the object changes state and matches signals. zx_object_wait_async syscall.
