Expand description

A container for I/O events.

Implementations§

source§

impl Events

source

pub fn new() -> Self

Create a new container for events, using the default capacity.

The default capacity is 1024.

§Examples
use polling::Events;

let events = Events::new();
source

pub fn with_capacity(capacity: NonZeroUsize) -> Self

Create a new container with the provided capacity.

§Examples
use polling::Events;
use std::num::NonZeroUsize;

let capacity = NonZeroUsize::new(1024).unwrap();
let events = Events::with_capacity(capacity);
source

pub fn iter(&self) -> impl Iterator<Item = Event> + '_

Create a new iterator over I/O events.

This returns all of the events in the container, excluding the notification event.

§Examples
use polling::{Event, Events, Poller};
use std::time::Duration;

let poller = Poller::new()?;
let mut events = Events::new();

poller.wait(&mut events, Some(Duration::from_secs(0)))?;
assert!(events.iter().next().is_none());
source

pub fn clear(&mut self)

Delete all of the events in the container.

§Examples
use polling::{Event, Events, Poller};

let poller = Poller::new()?;
let mut events = Events::new();

/* register some sources */

poller.wait(&mut events, None)?;

events.clear();
source

pub fn len(&self) -> usize

Returns the number of events in the container.

§Examples
use polling::Events;

let events = Events::new();
assert_eq!(events.len(), 0);
source

pub fn is_empty(&self) -> bool

Returns true if the container contains no events.

§Examples
use polling::Events;

let events = Events::new();
assert!(events.is_empty());
source

pub fn capacity(&self) -> NonZeroUsize

Get the total capacity of the list.

§Examples
use polling::Events;
use std::num::NonZeroUsize;

let cap = NonZeroUsize::new(10).unwrap();
let events = Events::with_capacity(std::num::NonZeroUsize::new(10).unwrap());
assert_eq!(events.capacity(), cap);
