|
|
|
<p><a href="struct.Slice.html#method.new" title="Slice::new"><code>Slice::new</code></a> constructs a distribution referencing a slice and uniformly
|
|
|
samples references from the items in the slice. It may do extra work up
|
|
|
front to make sampling of multiple values faster; if only one sample from
|
|
|
the slice is required, <a href="../seq/trait.SliceRandom.html#tymethod.choose"><code>SliceRandom::choose</code></a> can be more efficient.</p>
|
|
|
<p>Steps are taken to avoid bias which might be present in naive
|
|
|
implementations; for example <code>slice[rng.gen() % slice.len()]</code> samples from
|
|
|
the slice, but may be more likely to select numbers in the low range than
|
|
|
other values.</p>
|
|
|
<p>This distribution samples with replacement; each sample is independent.
|
|
|
Sampling without replacement requires state to be retained, and therefore
|
|
|
cannot be handled by a distribution; you should instead consider methods
|
|
|
on <a href="../seq/trait.SliceRandom.html"><code>SliceRandom</code></a>, such as <a href="../seq/trait.SliceRandom.html#tymethod.choose_multiple"><code>SliceRandom::choose_multiple</code></a>.</p>
