pub struct Channel<T> { /* private fields */ }
Expand description
The receiving end of the channel
This is the event source to be inserted into your EventLoop
.
Implementations§

sourcepub fn recv(&self) -> Result<T, RecvError>
pub fn recv(&self) -> Result<T, RecvError>
Proxy for mpsc::Receiver::recv
to manually poll events.
Note: Normally you would want to use the Channel
by inserting
it into an event loop instead. Use this for example to immediately
dispatch pending events after creation.
sourcepub fn try_recv(&self) -> Result<T, TryRecvError>
pub fn try_recv(&self) -> Result<T, TryRecvError>
Proxy for mpsc::Receiver::try_recv
to manually poll events.
Note: Normally you would want to use the Channel
by inserting
it into an event loop instead. Use this for example to immediately
dispatch pending events after creation.

notifications. These are opt-in because
they require more expensive checks, and almost all sources will not need these notificationssource§fn before_sleep(&mut self) -> Result<Option<(Readiness, Token)>>
