Struct mio::Interest [−][src]
pub struct Interest(_);
Expand description
Interest used in registering.
Interest are used in registering event::Source
s 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
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.
