[][src]Struct mio::Interest

pub struct Interest(_);

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.


impl Interest[src]

pub const READABLE: Interest[src]

Returns a Interest set representing readable interests.

pub const WRITABLE: Interest[src]

Returns a Interest set representing writable interests.

pub const fn add(self, other: Interest) -> Interest[src]

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);

pub fn remove(self, other: Interest) -> Option<Interest>[src]

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();

// 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);

pub const fn is_readable(self) -> bool[src]

Returns true if the value includes readable readiness.

pub const fn is_writable(self) -> bool[src]

Returns true if the value includes writable readiness.

pub const fn is_aio(self) -> bool[src]

Returns true if Interest contains AIO readiness

pub const fn is_lio(self) -> bool[src]

Returns true if Interest contains LIO readiness
