Struct embassy_time::Timer

source · [−]

pub struct Timer { /* private fields */ }

Expand description

A future that completes at a specified Instant.

Implementations

source

impl Timer

source

pub fn at(expires_at: Instant) -> Self

Expire at specified Instant

source

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;
}
