pub struct Interest(/* private fields */);
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§
source§impl Interest
impl Interest
sourcepub const PRIORITY: Interest = _
pub const PRIORITY: Interest = _
Returns a Interest
set representing priority completion interests.
sourcepub const fn add(self, other: Interest) -> Interest
pub const fn add(self, other: Interest) -> Interest
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);
sourcepub fn remove(self, other: Interest) -> Option<Interest>
pub fn remove(self, other: Interest) -> Option<Interest>
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);
sourcepub const fn is_readable(self) -> bool
pub const fn is_readable(self) -> bool
Returns true if the value includes readable readiness.
sourcepub const fn is_writable(self) -> bool
pub const fn is_writable(self) -> bool
Returns true if the value includes writable readiness.
sourcepub const fn is_priority(self) -> bool
pub const fn is_priority(self) -> bool
Returns true if Interest
contains priority readiness.
