Struct mio::event::Events

pub struct Events { /* private fields */ }

A collection of readiness events.

Events is passed as an argument to Poll::poll and will be used to receive any new readiness events received since the last poll. Usually, a single Events instance is created at the same time as a Poll and reused on each call to Poll::poll.

See Poll for more documentation on polling.

Examples

use mio::{Events, Poll};
use std::time::Duration;

let mut events = Events::with_capacity(1024);
let mut poll = Poll::new()?;

// Register `event::Source`s with `poll`.

poll.poll(&mut events, Some(Duration::from_millis(100)))?;

for event in events.iter() {
    println!("Got an event for {:?}", event.token());
}

Implementations

impl Events

pub fn with_capacity(capacity: usize) -> Events

Return a new Events capable of holding up to capacity events.

Examples

use mio::Events;

let events = Events::with_capacity(1024);
assert_eq!(1024, events.capacity());

pub fn capacity(&self) -> usize

Returns the number of Event values that self can hold.

use mio::Events;

let events = Events::with_capacity(1024);
assert_eq!(1024, events.capacity());

pub fn is_empty(&self) -> bool

Returns true if self contains no Event values.

Examples

use mio::Events;

let events = Events::with_capacity(1024);
assert!(events.is_empty());

pub fn iter(&self) -> Iter<'_>

Returns an iterator over the Event values.

Examples

use mio::{Events, Poll};
use std::time::Duration;

let mut events = Events::with_capacity(1024);
let mut poll = Poll::new()?;

// Register handles with `poll`.

poll.poll(&mut events, Some(Duration::from_millis(100)))?;

for event in events.iter() {
    println!("Got an event for {:?}", event.token());
}

pub fn clear(&mut self)

Clearing all Event values from container explicitly.

Notes

Events are cleared before every poll, so it is not required to call this manually.

Examples

use mio::{Events, Poll};
use std::time::Duration;

let mut events = Events::with_capacity(1024);
let mut poll = Poll::new()?;

// Register handles with `poll`.

poll.poll(&mut events, Some(Duration::from_millis(100)))?;

// Clear all events.
events.clear();
assert!(events.is_empty());

Trait Implementations

impl Debug for Events

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

Formats the value using the given formatter.

impl<'a> IntoIterator for &'a Events

type Item = &'a Event

The type of the elements being iterated over.

type IntoIter = Iter<'a>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
