[−][src]Struct mio::event::Events
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 poll = Poll::new()?; assert_eq!(0, events.len()); // Register `Evented` handles with `poll` poll.poll(&mut events, Some(Duration::from_millis(100)))?; for event in &events { println!("event={:?}", event); }
Methods
impl Events
[src]
pub fn with_capacity(capacity: usize) -> Events
[src]
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
[src]
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
[src]
Returns true
if self
contains no Event
values.
Examples
use mio::Events; let events = Events::with_capacity(1024); assert!(events.is_empty());
ⓘImportant traits for Iter<'a>pub fn iter(&self) -> Iter
[src]
Returns an iterator over the Event
values.
Examples
use mio::{Events, Poll}; use std::time::Duration; let mut events = Events::with_capacity(1024); let poll = Poll::new()?; // Register handles with `poll` poll.poll(&mut events, Some(Duration::from_millis(100)))?; for event in events.iter() { println!("event={:?}", event); }
pub fn clear(&mut self)
[src]
Clearing all Event
values from container explicitly.
Examples
use mio::{Events, Poll}; use std::time::Duration; let mut events = Events::with_capacity(1024); let poll = Poll::new()?; // Register handles with `poll` for _ in 0..2 { events.clear(); poll.poll(&mut events, Some(Duration::from_millis(100)))?; for event in events.iter() { println!("event={:?}", event); } }
