Trait FutureTimeout 

pub trait FutureTimeout<T>: Future<Output = T> + Sized {
    // Provided method
    fn timeout(self, duration: Duration) -> impl Future<Output = Option<T>> { ... }
}

This trait adds a timeout method to all futures.

Provided Methods

fn timeout(self, duration: Duration) -> impl Future<Output = Option<T>>

This method, implemented for all futures, returns another future which yields None if the inner future takes too long to yield its output.

If the inner future yields in time, its output is in turn yielded in Some(_).

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
