Struct Waker 

pub struct Waker { /* private fields */ }

Cloneable handle that interrupts an in-progress EventSource::poll or EventSource::read.

A waker is bound to one source at construction time. Calling Waker::wake makes the source’s readiness wait return Interrupted; multiple wake calls may coalesce into one interruption. The handle is cheap to clone and can be sent to other threads.

Implementations

impl Waker

pub fn wake(&self) -> Result<()>

Interrupt the EventSource this waker is bound to.

A blocked EventSource::poll returns Ok(false) and a blocked EventSource::read returns an io::ErrorKind::Interrupted error. The wake does not enqueue an Event and does not mutate decoder state.

Returns any platform error produced while signalling the wake handle.

Trait Implementations

impl Clone for Waker

fn clone(&self) -> Waker

Returns a duplicate of the value.

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

Performs copy-assignment from source.
