Enum read_write_store::timeout::Timeout

pub enum Timeout {
    DontBlock,
    BlockUntil(Instant),
    BlockIndefinitely,
}

A timeout (or lack thereof) describing how blocking operations should behave.

Variants

DontBlock

Disallows blocking for a contended resource.

BlockUntil(Instant)

Allows blocking for a contended resource until the given time has passed.

Tuple Fields of BlockUntil

0: Instant

BlockIndefinitely

Allows blocking for a contended resource indefinitely.

Implementations

impl Timeout

pub fn block_for(duration: Duration) -> Self

Creates a new timeout that lasts for the provided duration, starting now.

Example

let first_timeout = Timeout::BlockUntil(Instant::now());
let second_timeout = Timeout::block_for(Duration::from_secs(1));
assert!(first_timeout < second_timeout);

pub fn block_for_millis(millis: u64) -> Self

Creates a new timeout that lasts for the provided number of milliseconds, starting now.

Example

let first_timeout = Timeout::BlockUntil(Instant::now());
let second_timeout = Timeout::block_for_millis(1000);
assert!(first_timeout < second_timeout);
