<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

when the next value may be ready.</p>
|
||
</li>
|
||
<li>
|
||
<p><code>Poll::Ready(Some(val))</code> means that the stream has successfully

produced a value, <code>val</code>, and may produce further values on subsequent
|
||
<code>poll_next</code> calls.</p>
|
||
</li>
|
||
<li>
|
||
<p><code>Poll::Ready(None)</code> means that the stream has terminated, and

|
||
</li>
|
||
</ul>
|
||
<h1 id="panics" class="section-header"><a href="#panics">Panics</a></h1>
|
||
<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
|
||
calls.</p>

or more than the upper bound of elements.</p>
|
||
<p><code>size_hint()</code> is primarily intended to be used for optimizations such as
|

reserving space for the elements of the stream, but must not be

trusted to e.g., omit bounds checks in unsafe code. An incorrect

implementation of <code>size_hint()</code> should not lead to memory safety
|

violations.</p>
|

<p>That said, the implementation should provide a correct estimation,

because otherwise it would be a violation of the trait's protocol.</p>

<p>The default implementation returns <code>(0, </code><a href="https://doc.rust-lang.org/nightly/core/option/enum.Option.html#variant.None" title="None"><code>None</code></a><code>)</code> which is correct for any
