Trait Implementations§

source§

impl<T: Debug> Debug for Executor<T>

source§

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter. Read more
source§

impl<T> Drop for Executor<T>

source§

fn drop(&mut self)

Executes the destructor for this type. Read more
source§

impl<T> EventSource for Executor<T>

§

type Event = T

The type of events generated by your source.
§

type Metadata = ()

Some metadata of your event source Read more
§

type Ret = ()

The return type of the user callback Read more
§

type Error = ExecutorError

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

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

Process any relevant events Read more
source§

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

Register yourself to this poll instance Read more
source§

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

Re-register your file descriptors Read more
source§

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

Unregister your file descriptors Read more
source§

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
source§

fn before_sleep(&mut self) -> Result<Option<(Readiness, Token)>>

Notification that a single poll is about to begin Read more
source§

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 Read more
