pub trait FusedStream: Stream { }
Available on unstable only.
Expand description

A stream that always continues to yield None when exhausted.

Calling next on a fused stream that has returned None once is guaranteed to return None again. This trait should be implemented by all streams that behave this way because it allows optimizing Stream::fuse.

Note: In general, you should not use FusedStream in generic bounds if you need a fused stream. Instead, you should just call Stream::fuse on the stream. If the stream is already fused, the additional Fuse wrapper will be a no-op with no performance penalty.
