Timer facilities for Rust's async story

Accuracy

Regular timers that do not rely on async event loop tend to be on par with user space timers like in tokio. If that's not suitable for you you should enable event loop based timers which in most cases give you the most accurate timers possible on unix platforms (See features.)

Features

• tokio1 - Enables event loop based timers using tokio, providing higher resolution timers on unix platforms.
• c_wrapper - Uses C shim to create bindings to platform API, which may be more reliable than libc.
• std - Enables usage of std types (e.g. Error)
• stream - Enables Stream implementation for Interval

Examples

Timed

```rust async fn job() { }

async fn dojob() { let work = unsafe { asynctimer::Timed::platformnewunchecked(job(), core::time::Duration::from_secs(1)) };

match work.await {
    Ok(_) => println!("I'm done!"),
    //You can retry by polling `expired`
    Err(expired) => println!("Job expired: {}", expired),
}

} ```

Interval

```rust async fn job() { }

async fn doawhile() { let mut times: u8 = 0; let mut interval = asynctimer::Interval::platformnew(core::time::Duration::from_secs(1));

while times < 5 {
    job().await;
    interval.wait().await;
    times += 1;
}

} ```
