Trait FusedStream 

pub trait FusedStream: Stream {
    // Required method
    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

Returns true if the stream should no longer be polled.

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.
