[−][src]Struct mio::PollOpt
Options supplied when registering an Evented
handle with Poll
PollOpt
values can be combined together using the various bitwise
operators.
For high level documentation on polling and poll options, see Poll
.
Examples
use mio::PollOpt; let opts = PollOpt::edge() | PollOpt::oneshot(); assert!(opts.is_edge()); assert!(opts.is_oneshot()); assert!(!opts.is_level());
Implementations
impl PollOpt
[src]
pub fn empty() -> PollOpt
[src]
Return a PollOpt
representing no set options.
See Poll
for more documentation on polling.
Examples
use mio::PollOpt; let opt = PollOpt::empty(); assert!(!opt.is_level());
pub fn edge() -> PollOpt
[src]
Return a PollOpt
representing edge-triggered notifications.
See Poll
for more documentation on polling.
Examples
use mio::PollOpt; let opt = PollOpt::edge(); assert!(opt.is_edge());
pub fn level() -> PollOpt
[src]
Return a PollOpt
representing level-triggered notifications.
See Poll
for more documentation on polling.
Examples
use mio::PollOpt; let opt = PollOpt::level(); assert!(opt.is_level());
pub fn oneshot() -> PollOpt
[src]
Return a PollOpt
representing oneshot notifications.
See Poll
for more documentation on polling.
Examples
use mio::PollOpt; let opt = PollOpt::oneshot(); assert!(opt.is_oneshot());
pub fn is_edge(&self) -> bool
[src]
Returns true if the options include edge-triggered notifications.
See Poll
for more documentation on polling.
Examples
use mio::PollOpt; let opt = PollOpt::edge(); assert!(opt.is_edge());
pub fn is_level(&self) -> bool
[src]
Returns true if the options include level-triggered notifications.
See Poll
for more documentation on polling.
Examples
use mio::PollOpt; let opt = PollOpt::level(); assert!(opt.is_level());
pub fn is_oneshot(&self) -> bool
[src]
Returns true if the options includes oneshot.
See Poll
for more documentation on polling.
Examples
use mio::PollOpt; let opt = PollOpt::oneshot(); assert!(opt.is_oneshot());
pub fn contains(&self, other: PollOpt) -> bool
[src]
Returns true if self
is a superset of other
.
other
may represent more than one option, in which case the function
only returns true if self
contains all of the options specified in
other
.
See Poll
for more documentation on polling.
Examples
use mio::PollOpt; let opt = PollOpt::oneshot(); assert!(opt.contains(PollOpt::oneshot())); assert!(!opt.contains(PollOpt::edge()));
use mio::PollOpt; let opt = PollOpt::oneshot() | PollOpt::edge(); assert!(opt.contains(PollOpt::oneshot())); assert!(opt.contains(PollOpt::edge()));
use mio::PollOpt; let opt = PollOpt::oneshot() | PollOpt::edge(); assert!(!PollOpt::oneshot().contains(opt)); assert!(opt.contains(opt)); assert!((opt | PollOpt::level()).contains(opt));
pub fn insert(&mut self, other: PollOpt)
[src]
Adds all options represented by other
into self
.
This is equivalent to *self = *self | other
.
Examples
use mio::PollOpt; let mut opt = PollOpt::empty(); opt.insert(PollOpt::oneshot()); assert!(opt.is_oneshot());
pub fn remove(&mut self, other: PollOpt)
[src]
Removes all options represented by other
from self
.
This is equivalent to *self = *self & !other
.
Examples
use mio::PollOpt; let mut opt = PollOpt::oneshot(); opt.remove(PollOpt::oneshot()); assert!(!opt.is_oneshot());
