Struct embassy_time::Timer

pub struct Timer { /* private fields */ }

A future that completes at a specified Instant.

Implementations

impl Timer

pub fn at(expires_at: Instant) -> Self

Expire at specified Instant

pub fn after(duration: Duration) -> Self

Expire after specified Duration. This can be used as a sleep abstraction.

Example:

use embassy_time::{Duration, Timer};

#[embassy_executor::task]
async fn demo_sleep_seconds() {
    // suspend this task for one second.
    Timer::after(Duration::from_secs(1)).await;
}

pub fn after_ticks(ticks: u64) -> Self

Expire after the specified number of ticks.

This method is a convenience wrapper for calling Timer::after(Duration::from_ticks()). For more details, refer to Timer::after() and Duration::from_ticks().

pub fn after_nanos(nanos: u64) -> Self

Expire after the specified number of nanoseconds.

This method is a convenience wrapper for calling Timer::after(Duration::from_nanos()). For more details, refer to Timer::after() and Duration::from_nanos().

pub fn after_micros(micros: u64) -> Self

Expire after the specified number of microseconds.

This method is a convenience wrapper for calling Timer::after(Duration::from_micros()). For more details, refer to Timer::after() and Duration::from_micros().

pub fn after_millis(millis: u64) -> Self

Expire after the specified number of milliseconds.

This method is a convenience wrapper for calling Timer::after(Duration::from_millis()). For more details, refer to Timer::after and Duration::from_millis().

pub fn after_secs(secs: u64) -> Self

Expire after the specified number of seconds.

This method is a convenience wrapper for calling Timer::after(Duration::from_secs()). For more details, refer to Timer::after and Duration::from_secs().

Trait Implementations

impl Future for Timer

type Output = ()

The type of value produced on completion.

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.
