Struct nix::sys::epoll::EpollTimeout

pub struct EpollTimeout(/* private fields */);

PollTimeout argument for polling.

Implementations

impl PollTimeout

pub const NONE: Self = _

Blocks indefinitely.

Specifying a negative value in timeout means an infinite timeout.

pub const ZERO: Self = _

Returns immediately.

Specifying a timeout of zero causes poll() to return immediately, even if no file descriptors are ready.

pub const MAX: Self = _

Blocks for at most i32::MAX milliseconds.

pub fn is_none(&self) -> bool

Returns if self equals PollTimeout::NONE.

pub fn is_some(&self) -> bool

Returns if self does not equal PollTimeout::NONE.

pub fn as_millis(&self) -> Option<u32>

Returns the timeout in milliseconds if there is some, otherwise returns None.

pub fn duration(&self) -> Option<Duration>

Returns the timeout as a Duration if there is some, otherwise returns None.
