    pub fn wake_by_ref(self: &Arc<Self>) { ... }
}

🔬 This is a nightly-only experimental API. (wake_trait)

The implementation of waking a task on an executor.

This trait can be used to create a Waker. An executor can define an implementation of this trait, and use that to construct a Waker to pass to the tasks that are executed on that executor.

This trait is a memory-safe and ergonomic alternative to constructing a RawWaker. It supports the common executor design in which the data used to wake up a task is stored in an Arc. Some executors (especially those for embedded systems) cannot use this API, which is why RawWaker exists as an alternative for those systems.

Required methods

pub fn wake(self: Arc<Self>)

🔬 This is a nightly-only experimental API. (wake_trait)

Provided methods

pub fn wake_by_ref(self: &Arc<Self>)

🔬 This is a nightly-only experimental API. (wake_trait)

Wake this task without consuming the waker.

If an executor supports a cheaper way to wake without consuming the waker, it should override this method. By default, it clones the Arc and calls wake on the clone.
