|
||||
<p>This function is the dual for the <code>TryStream::try_fold()</code> adapter: while
|
||||
<code>TryStream::try_fold()</code> reduces a <code>TryStream</code> to one single value,
|
||||
<code>try_unfold()</code> creates a <code>TryStream</code> from a seed value.</p>
|
||||
<p><code>try_unfold()</code> will call the provided closure with the provided seed, then
|
||||
wait for the returned <code>TryFuture</code> to complete with <code>(a, b)</code>. It will then
|
||||
yield the value <code>a</code>, and use <code>b</code> as the next internal state.</p>
|
||||
<p>If the closure returns <code>None</code> instead of <code>Some(TryFuture)</code>, then the
|
||||
<code>try_unfold()</code> will stop producing items and return <code>Poll::Ready(None)</code> in
|
||||
future calls to <code>poll()</code>.</p>
|
||||
<p>In case of error generated by the returned <code>TryFuture</code>, the error will be
|
||||
returned by the <code>TryStream</code>. The <code>TryStream</code> will then yield
|
||||
<code>Poll::Ready(None)</code> in future calls to <code>poll()</code>.</p>
|
||||
<p>This function can typically be used when wanting to go from the “world of
|
||||
futures” to the “world of streams”: the provided closure can build a
|
||||
<code>TryFuture</code> using other library functions working on futures, and
|
||||
<code>try_unfold()</code> will turn it into a <code>TryStream</code> by repeating the operation.</p>

|
||||
<p>This function is the dual for the <code>Stream::fold()</code> adapter: while
|
||||
<code>Stream::fold()</code> reduces a <code>Stream</code> to one single value, <code>unfold()</code> creates a
|
||||
<code>Stream</code> from a seed value.</p>
|
||||
<p><code>unfold()</code> will call the provided closure with the provided seed, then wait
|
||||
for the returned <code>Future</code> to complete with <code>(a, b)</code>. It will then yield the
|
||||
value <code>a</code>, and use <code>b</code> as the next internal state.</p>
|
||||
<p>If the closure returns <code>None</code> instead of <code>Some(Future)</code>, then the <code>unfold()</code>
|
||||
will stop producing items and return <code>Poll::Ready(None)</code> in future
|
||||
calls to <code>poll()</code>.</p>
|
||||
<p>This function can typically be used when wanting to go from the “world of
|
||||
futures” to the “world of streams”: the provided closure can build a
|
||||
<code>Future</code> using other library functions working on futures, and <code>unfold()</code>
|
||||
will turn it into a <code>Stream</code> by repeating the operation.</p>
