Struct `PollTimeout`

pub struct PollTimeout(/* private field */);

PollTimeout argument for polling.

Implementations

`impl PollTimeout`

const NONE: Self = _;: Blocks indefinitely.

Specifying a negative value in timeout means an infinite timeout.
const ZERO: Self = _;: Returns immediately.

Specifying a timeout of zero causes poll() to return immediately, even if no file descriptors are ready.
const MAX: Self = _;: Blocks for at most i32::MAX milliseconds.
fn is_none(&self) -> bool: Returns if self equals PollTimeout::NONE.
fn is_some(&self) -> bool: Returns if self does not equal PollTimeout::NONE.
fn as_millis(&self) -> Option<u32>: Returns the timeout in milliseconds if there is some, otherwise returns None.
fn duration(&self) -> Option<Duration>: Returns the timeout as a Duration if there is some, otherwise returns None.
