<h1 id="return-value" class="section-header"><a href="#return-value">Return value</a></h1>
<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
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
<code>poll_next</code> should not be invoked again.</p>
</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>

<p>Specifically, <code>size_hint()</code> returns a tuple where the first element

<h1 id="implementation-notes" class="section-header"><a href="#implementation-notes">Implementation notes</a></h1>
<p>It is not enforced that a stream implementation yields the declared
number of elements. A buggy stream may yield less than the lower bound
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
stream.</p>
