Struct CallbackWaker 

pub struct CallbackWaker<F>
where
    F: Fn() + Send + Sync + Clone + 'static,
{ /* private fields */ }

A waker that uses a callback function.

This is useful for integrating with custom event loop systems.

impl<F> CallbackWaker<F>

where F: Fn() + Send + Sync + Clone + 'static,

pub fn new(callback: F) -> Self

Create a new callback waker.

pub fn invalidate(&self)

Invalidate this waker.

where F: Fn() + Send + Sync + Clone + 'static,

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<F> EventLoopWaker for CallbackWaker<F>

where F: Fn() + Send + Sync + Clone + 'static,

fn wake(&self)
