Struct tokio_timer::Delay [] [src]

pub struct Delay { /* fields omitted */ }

A future that completes at a specified instant in time.

Instances of Delay perform no work and complete with () once the specified deadline has been reached.

Delay has a resolution of one millisecond and should not be used for tasks that require high-resolution timers.

Methods

impl Delay
[src]

[src]

Create a new Delay instance that elapses at deadline.

Only millisecond level resolution is guaranteed. There is no guarantee as to how the sub-millisecond portion of deadline will be handled. Delay should not be used for high-resolution timer use cases.

[src]

Returns the instant at which the future will complete.

[src]

Returns true if the Delay has elapsed

A Delay is elapsed when the requested duration has elapsed.

[src]

Reset the Delay instance to a new deadline.

Calling this function allows changing the instant at which the Delay future completes without having to create new associated state.

This function can be called both before and after the future has completed.
