impl EventSource for LibSeatSessionNotifier

type Event = Event

The type of events generated by your source.

type Metadata = ()

Some metadata of your event source

type Ret = ()

The return type of the user callback

type Error = Error

The error type returned from process_events() (not the user callback!).

fn process_events<F>( &mut self, readiness: Readiness, token: Token, callback: F, ) -> Result<PostAction, Error>

where F: FnMut(SessionEvent, &mut ()),

Process any relevant events

fn register( &mut self, poll: &mut Poll, factory: &mut TokenFactory, ) -> Result<()>

Register yourself to this poll instance

fn reregister( &mut self, poll: &mut Poll, factory: &mut TokenFactory, ) -> Result<()>

Re-register your file descriptors

fn unregister(&mut self, poll: &mut Poll) -> Result<()>

Unregister your file descriptors

const NEEDS_EXTRA_LIFECYCLE_EVENTS: bool = false

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>

Notification that a single poll is about to begin

fn before_handle_events(&mut self, events: EventIterator<'_>)

Notification that polling is complete, and EventSource::process_events will be called with the given events for this source. The iterator may be empty, which indicates that no events were generated for this source
