| <code>None</code> if the stream is exhausted.</p> |
| <h5 id="return-value"><a href="#return-value">Return value</a></h5> |
| <p>There are several possible return values, each indicating a distinct |
| stream state:</p> |
| <ul> |
| <li> |
| <p><code>Poll::Pending</code> means that this stream’s next value is not ready |
| yet. Implementations will ensure that the current task will be notified |
| when the next value may be ready.</p> |
| </li> |
| <li> |
| <p><code>Poll::Ready(Some(val))</code> means that the stream has successfully |

| <code>poll_next</code> calls.</p> |
| </li> |
| <li> |
| <p><code>Poll::Ready(None)</code> means that the stream has terminated, and |
| <code>poll_next</code> should not be invoked again.</p> |
| </li> |
| </ul> |
| <h5 id="panics"><a href="#panics">Panics</a></h5> |
| <p>Once a stream has finished (returned <code>Ready(None)</code> from <code>poll_next</code>), calling its |
| <code>poll_next</code> method again may panic, block forever, or cause other kinds of |
| problems; the <code>Stream</code> trait places no requirements on the effects of |
| such a call. However, as the <code>poll_next</code> method is not marked <code>unsafe</code>, |
| Rust’s usual rules apply: calls must never cause undefined behavior |
| (memory corruption, incorrect use of <code>unsafe</code> functions, or the like), |
| regardless of the stream’s state.</p> |
| <p>If this is difficult to guard against then the <a href="https://docs.rs/futures/0.3/futures/stream/trait.StreamExt.html#method.fuse"><code>fuse</code></a> adapter can be used |
| to ensure that <code>poll_next</code> always returns <code>Ready(None)</code> in subsequent |
