Module embassy_time::queue

Timer queue implementation

This module defines the interface a timer queue needs to implement to power the embassy_time module.

Implementing a timer queue

• Define a struct MyTimerQueue
• Implement TimerQueue for it
• Register it as the global timer queue with timer_queue_impl.

Linkage details

Check the documentation of the driver module for more information.

Similarly to driver, if there is none or multiple timer queues in the crate tree, linking will fail.

Example

use core::task::Waker;

use embassy_time::Instant;
use embassy_time::queue::{TimerQueue};

struct MyTimerQueue{}; // not public!
embassy_time::timer_queue_impl!(static QUEUE: MyTimerQueue = MyTimerQueue{});

impl TimerQueue for MyTimerQueue {
    fn schedule_wake(&'static self, at: Instant, waker: &Waker) {
        todo!()
    }
}
