# Trait futures_core::stream::FusedStream [−] [src]

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

A stream 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` [src]

Returns `true` if the stream should no longer be polled.
