2472 <h5 id="current-implementation-8"><a class="doc-anchor" href="#current-implementation-8">§</a>Current implementation</h5>
2473 <p>The current implementation is based on <a href="https://github.com/Voultapher/driftsort">driftsort</a> by Orson Peters and Lukas Bergdoll, which
2474 combines the fast average case of quicksort with the fast worst case and partial run
2475 detection of mergesort, achieving linear time on fully sorted and reversed inputs. On inputs
2476 with k distinct elements, the expected time to sort the data is <em>O</em>(<em>n</em> * log(<em>k</em>)).</p>
2477 <p>The auxiliary memory allocation behavior depends on the input length. Short slices are
2478 handled without allocation, medium sized slices allocate <code>self.len()</code> and beyond that it
2479 clamps at <code>self.len() / 2</code>.</p>
2480 <h5 id="panics-39"><a class="doc-anchor" href="#panics-39">§</a>Panics</h5>
2481 <p>May panic if the implementation of <a href="https://doc.rust-lang.org/nightly/core/cmp/trait.Ord.html" title="trait core::cmp::Ord"><code>Ord</code></a> for <code>T</code> does not implement a <a href="https://en.wikipedia.org/wiki/Total_order">total order</a>, or if
2482 the <a href="https://doc.rust-lang.org/nightly/core/cmp/trait.Ord.html" title="trait core::cmp::Ord"><code>Ord</code></a> implementation itself panics.</p>
2483 <p>All safe functions on slices preserve the invariant that even if the function panics, all
