<p>The <code>ArrayVec</code> is a vector backed by a fixed size array. It keeps track of
|
|||
|
|
the number of initialized elements.</p>
|
|||
|
|
<p>The vector is a contiguous value that you can store directly on the stack
|
|||
|
|
if needed.</p>
|
|||
|
|
<p>It offers a simple API but also dereferences to a slice, so
|
|||
|
|
that the full slice API is available.</p>
|
|||
|
|
<p>ArrayVec can be converted into a by value iterator.</p>

<p>The current algorithm is based on <a href="https://github.com/orlp/pdqsort">pattern-defeating quicksort</a> by Orson Peters,
|
|||
|
|
which combines the fast average case of randomized quicksort with the fast worst case of
|
|||
|
|
heapsort, while achieving linear time on slices with certain patterns. It uses some
|
|||
|
|
randomization to avoid degenerate cases, but with a fixed seed to always provide
|

|
|
deterministic behavior.</p>
