[][src]Struct mio::PollOpt

pub struct 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());
