Struct popol::Sources

pub struct Sources<K> { /* fields omitted */ }

Keeps track of sources to poll.

Implementations

impl<K: Eq + Clone> Sources<K>

pub fn new() -> Self

Creates a new set of sources to poll.

pub fn with_capacity(cap: usize) -> Self

Creates a new set of sources to poll, with the given capacity. Use this if you have a lot of sources to poll.

pub fn len(&self) -> usize

Return the number of registered sources.

pub fn is_empty(&self) -> bool

Return whether the source registry is empty.

pub fn register(&mut self, key: K, fd: &impl AsRawFd, events: Interest)

Register a new source, with the given key, and wait for the specified events.

pub fn unregister(&mut self, key: &K)

Unregister a source, given its key.

pub fn set(&mut self, key: &K, events: Interest) -> bool

Set the events to poll for on a source identified by its key.

pub fn unset(&mut self, key: &K, events: Interest) -> bool

Unset event interests on a source.

pub fn get_mut(&mut self, key: &K) -> Option<&mut Source>

Get a source by key.

pub fn wait_timeout(
    &mut self,
    events: &mut Events<K>,
    timeout: Duration
) -> Result<(), Error>

Wait for readiness events on the given list of sources. If no event is returned within the given timeout, returns an error of kind io::ErrorKind::TimedOut.

pub fn wait(&mut self, events: &mut Events<K>) -> Result<(), Error>

Wait for readiness events on the given list of sources, or until the call is interrupted.

Trait Implementations

fn clone(&self) -> Sources<K>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<K: Debug> Debug for Sources<K>

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

Formats the value using the given formatter.
