Struct tokio_core::reactor::Timeout [] [src]

#[must_use = "futures do nothing unless polled"]
pub struct Timeout { /* fields omitted */ }

A future representing the notification that a timeout has occurred.

Timeouts are created through the Timeout::new or Timeout::new_at methods indicating when a timeout should fire at. Note that timeouts are not intended for high resolution timers, but rather they will likely fire some granularity after the exact instant that they're otherwise indicated to fire at.

Methods

impl Timeout
[src]

[src]

Creates a new timeout which will fire at dur time into the future.

This function will return a Result with the actual timeout object or an error. The timeout object itself is then a future which will be set to fire at the specified point in the future.

[src]

Creates a new timeout which will fire at the time specified by at.

This function will return a Result with the actual timeout object or an error. The timeout object itself is then a future which will be set to fire at the specified point in the future.

[src]

Resets this timeout to an new timeout which will fire at the time specified by at.

This method is usable even of this instance of Timeout has "already fired". That is, if this future has resolved, calling this method means that the future will still re-resolve at the specified instant.

If at is in the past then this future will immediately be resolved (when poll is called).

Note that if any task is currently blocked on this future then that task will be dropped. It is required to call poll again after this method has been called to ensure that a task is blocked on this future.
