    Inspect<IntoFuture<Fut>, InspectErrFn<F>>: FusedFuture, 

fn is_terminated(&self) -> bool

Returns true if the underlying future should no longer be polled.

impl<Fut, F> Future for InspectErr<Fut, F> where
    Inspect<IntoFuture<Fut>, InspectErrFn<F>>: Future, 

type Output = <Inspect<IntoFuture<Fut>, InspectErrFn<F>> as Future>::Output
