Struct safina_timer::DeadlineFuture

source · [−]

pub struct DeadlineFuture<Fut: Future + Unpin> { /* private fields */ }

Expand description

A future wrapper that returns DeadlineExceeded at a specified deadline.

It is returned by with_deadline and with_timeout.

Implementations

source

impl<Fut: Future + Unpin> DeadlineFuture<Fut>

source

pub fn new(inner: Fut, deadline: Instant) -> Self

Makes a future that awaits inner, but returns DeadlineError after deadline.

Note that inner must be Unpin. Use std::boxed::Box::pin to make it Unpin. Or use pin_utils::pin_mut to do it with unsafe code that does not allocate memory.

Trait Implementations

source

impl<Fut: Future + Unpin> Future for DeadlineFuture<Fut>

type Output = Result<Fut::Output, DeadlineError>

The type of value produced on completion.

source

fn poll(self: Pin<&mut Self>, cx: &mut Context<'_>) -> Poll<Self::Output>

Attempt to resolve the future to a final value, registering the current task for wakeup if the value is not yet available. Read more
