Trait futures_core::stream::FusedStream

pub trait FusedStream {
    fn is_terminated(&self) -> bool;
}

A Stream or TryStream which tracks whether or not the underlying stream should no longer be polled.

is_terminated will return true if a future should no longer be polled. Usually, this state occurs after poll_next (or try_poll_next) returned Poll::Ready(None). However, is_terminated may also return true if a stream has become inactive and can no longer make progress and should be ignored or dropped rather than being polled again.

Required methods

fn is_terminated(&self) -> bool

Returns true if the stream should no longer be polled.
