Struct Waker 

pub struct Waker(/* private fields */);

A handle into the event loop that any thread may hold; Waker::wake asks for a frame from wherever the app’s data arrived. Cheap to clone, and harmless after the loop has ended (a wake nobody hears is dropped). An app gets one in App::setup, a host from PumpRunner::waker.

Implementations

impl Waker

pub fn wake(&self)

Asks every window for a frame: the loop wakes, view runs and the frame is drawn. Safe from any thread and at any rate, since wakes coalesce into the loop’s next turn rather than queueing frames.
