<p>This module provides:</p>
|
|||
|
|
<ul>
|
|||
|
|
<li>[<code>seq::SliceRandom</code>] slice sampling and mutation</li>
|
|||
|
|
<li>[<code>seq::IteratorRandom</code>] iterator sampling</li>
|
|||
|
|
<li>[<code>seq::index::sample</code>] low-level API to choose multiple indices from
|
|||
|
|
<code>0..length</code></li>
|
|||
|
|
</ul>
|
|||
|
|
<p>Also see:</p>
|
|||
|
|
<ul>
|
|||
|
|
<li>[<code>distributions::weighted</code>] module which provides implementations of
|
|||
|
|
weighted index sampling.</li>
|
|||
|
|
</ul>
|
|||
|
|
<p>In order to make results reproducible across 32-64 bit architectures, all
|
|||
|
|
<code>usize</code> indices are sampled as a <code>u32</code> where possible (also providing a
|
|||
|
|
small performance boost in some cases).</p>
