Trait Timer 

pub trait Timer {
    type SleepFuture<'a>: Future<Output = ()>
       where Self: 'a;

    // Required method
    fn sleep(&self, duration: Duration) -> Self::SleepFuture<'_>;
}

Executor-agnostic sleep primitive.

simple-someip needs timed waits in two places: the Service Discovery announcement tick (1 s) and the client event-loop idle timeout (125 ms). Consumers provide a Timer at startup; on std + tokio this is a one-line wrapper around tokio::time::sleep, on embedded it is a one-line wrapper around embassy_time::Timer::after or similar.

Required Associated Types

type SleepFuture<'a>: Future<Output = ()> where Self: 'a

Future returned by Self::sleep.

As an associated GAT, consumers can require Send at use sites (where for<'a> Tm::SleepFuture<'a>: Send) without forcing every backend’s sleep future to be Send. Multi-threaded callers (Server::announcement_loop, the tokio Client) add the bound; single-threaded callers do not, accepting a !Send future from a backend like embassy_time.

Required Methods

fn sleep(&self, duration: Duration) -> Self::SleepFuture<'_>

Wait for at least duration before resolving. Implementations MAY overshoot but MUST NOT undershoot.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
