|
||
<p>You will rarely need to interact with this module directly unless you have
|
||
need to name one of the iterator types.</p>
|
||
<p>Parallel iterators make it easy to write iterator-like chains that
|
||
execute in parallel: typically all you have to do is convert the
|
||
first <code>.iter()</code> (or <code>iter_mut()</code>, <code>into_iter()</code>, etc) method into
|
||
<code>par_iter()</code> (or <code>par_iter_mut()</code>, <code>into_par_iter()</code>, etc). For
|
||
example, to compute the sum of the squares of a sequence of
|
||
integers, one might write:</p>
|
||
|
||
<pre class="rust rust-example-rendered">
|
||
<span class="kw">use</span> <span class="ident">rayon</span>::<span class="ident">prelude</span>::<span class="kw-2">*</span>;
|
||
<span class="kw">fn</span> <span class="ident">sum_of_squares</span>(<span class="ident">input</span>: <span class="kw-2">&</span>[<span class="ident">i32</span>]) <span class="op">-></span> <span class="ident">i32</span> {
|
||
<span class="ident">input</span>.<span class="ident">par_iter</span>()
|
||
.<span class="ident">map</span>(<span class="op">|</span><span class="ident">i</span><span class="op">|</span> <span class="ident">i</span> <span class="op">*</span> <span class="ident">i</span>)
|
||
.<span class="ident">sum</span>()
|
||
}</pre>
|
||
<p>Or, to increment all the integers in a slice, you could write:</p>
|
||
|
||
<pre class="rust rust-example-rendered">
|
||
<span class="kw">use</span> <span class="ident">rayon</span>::<span class="ident">prelude</span>::<span class="kw-2">*</span>;
|
||
<span class="kw">fn</span> <span class="ident">increment_all</span>(<span class="ident">input</span>: <span class="kw-2">&</span><span class="kw-2">mut</span> [<span class="ident">i32</span>]) {
|
||
<span class="ident">input</span>.<span class="ident">par_iter_mut</span>()
|
||
.<span class="ident">for_each</span>(<span class="op">|</span><span class="ident">p</span><span class="op">|</span> <span class="kw-2">*</span><span class="ident">p</span> <span class="op">+=</span> <span class="number">1</span>);
|
||
}</pre>
|
||
<p>To use parallel iterators, first import the traits by adding
|
||
something like <code>use rayon::prelude::*</code> to your module. You can
|
||
then call <code>par_iter</code>, <code>par_iter_mut</code>, or <code>into_par_iter</code> to get a
|
||
parallel iterator. Like a <a href="http://doc.rust-lang.org/std/iter/trait.Iterator.html">regular iterator</a>, parallel
|
||
iterators work by first constructing a computation and then
|
||
executing it.</p>
|
||
<p>In addition to <code>par_iter()</code> and friends, some types offer other
|
||
ways to create (or consume) parallel iterators:</p>
|
||
<ul>
|
||
<li>Slices (<code>&[T]</code>, <code>&mut [T]</code>) offer methods like <code>par_split</code> and
|
||
<code>par_windows</code>, as well as various parallel sorting
|
||
operations. See <a href="../slice/trait.ParallelSlice.html">the <code>ParallelSlice</code> trait</a> for the full list.</li>
|
||
<li>Strings (<code>&str</code>) offer methods like <code>par_split</code> and <code>par_lines</code>.
|
||
See <a href="../str/trait.ParallelString.html">the <code>ParallelString</code> trait</a> for the full list.</li>
|
||
<li>Various collections offer <a href="trait.ParallelExtend.html"><code>par_extend</code></a>, which grows a
|
||
collection given a parallel iterator. (If you don't have a
|
||
collection to extend, you can use <a href="trait.ParallelIterator.html#method.collect"><code>collect()</code></a> to create a new
|
||
one from scratch.)</li>
|
||
</ul>
|
||
<p>To see the full range of methods available on parallel iterators,
|
||
check out the <a href="trait.ParallelIterator.html"><code>ParallelIterator</code></a> and <a href="trait.IndexedParallelIterator.html"><code>IndexedParallelIterator</code></a>
|
||
traits.</p>
|
||
<p>If you'd like to build a custom parallel iterator, or to write your own
|
||
combinator, then check out the <a href="fn.split.html">split</a> function and the <a href="plumbing/index.html">plumbing</a> module.</p>
|
||
<p>Note: Several of the <code>ParallelIterator</code> methods rely on a <code>Try</code> trait which
|
||
has been deliberately obscured from the public API. This trait is intended
|
||
to mirror the unstable <code>std::ops::Try</code> with implementations for <code>Option</code> and
|
||
<code>Result</code>, where <code>Some</code>/<code>Ok</code> values will let those iterators continue, but
|
||
<code>None</code>/<code>Err</code> values will exit early.</p>
