pub struct Interest(_);
Expand description

Interest used in registering.

Interest are used in registering event::Sources with Poll, they indicate what readiness should be monitored for. For example if a socket is registered with readable interests and the socket becomes writable, no event will be returned from a call to poll.

Implementations

Returns a Interest set representing readable interests.

Returns a Interest set representing writable interests.

Returns a Interest set representing priority completion interests.

Add together two Interest.

This does the same thing as the BitOr implementation, but is a constant function.

use mio::Interest;

const INTERESTS: Interest = Interest::READABLE.add(Interest::WRITABLE);

Removes other Interest from self.

Returns None if the set would be empty after removing other.

use mio::Interest;

const RW_INTERESTS: Interest = Interest::READABLE.add(Interest::WRITABLE);

// As long a one interest remain this will return `Some`.
let w_interest = RW_INTERESTS.remove(Interest::READABLE).unwrap();
assert!(!w_interest.is_readable());
assert!(w_interest.is_writable());

// Removing all interests from the set will return `None`.
assert_eq!(w_interest.remove(Interest::WRITABLE), None);

// Its also possible to remove multiple interests at once.
assert_eq!(RW_INTERESTS.remove(RW_INTERESTS), None);

Returns true if the value includes readable readiness.

Returns true if the value includes writable readiness.

Returns true if Interest contains AIO readiness.

Returns true if Interest contains LIO readiness.

Returns true if Interest contains priority readiness.
