pub struct WritePipe { /* private fields */ }
Expand description
If the calloop
cargo feature is enabled, this can be used
as an EventSource
in a calloop event loop.

Whether this source needs to be sent the [
EventSource::before_sleep

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

fn before_handle_events(&mut self, events: EventIterator<'_>)
Notification that polling is complete, and [

be called with the given events for this source. The iterator may be empty,
