Struct InstrumentFuture

pub struct InstrumentFuture<F: Future> { /* private fields */ }

Wraps a future and determines exactly how long it took to execute

let my_fut: impl Future<Output = ()> = foobar();
let res = InstrumentFuture::new(my_fut).await;

// get the result of `my_fut`
res.result;

// print the elapsed time of `my_fut`
println!("my_fut took {:?}", res.elapsed);
