Trait WakeRef 

pub trait WakeRef {
    // Required method
    fn wake_by_ref(&self);
}

Wakers that can wake by reference. This trait is used to enable a Wake implementation for types that don’t own an underlying handle, like Arc<T> and &T.

This trait is implemented for most container and reference types, like &T where T: WakeRef, Box<T: WakeRef>, and Arc<T: WakeRef>.

Required Methods

fn wake_by_ref(&self)

Wake up the task by reference. In general Wake::wake should be preferred, if available, as it’s probably more efficient.

A Waker created by IntoWaker will call this method through Waker::wake_by_ref.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
