**Deprecated:** This is pre-rust 1.0 code. A majority of it will not compile or
otherwise work in modern Rust. It is kept here for legacy but is not recommended 
to learn from or use.

A comparison of different sort algorithms in Rust. This includes mergesort, 
quicksort, heapsort, insertion sort, selection sort, bubble sort and even bogo 
sort. The library comes with benchmarks for vectors of different sizes and for 
vectors that are already sorted or vectors where all elements are equivalent.
This library also comes with QuickCheck tests that check whether the result of 
a sorting algorithm is sorted. Each algorithm is also checked that it is 
stable/unstable depending on the algorithm used.

There is some documentation of the API: http://burntsushi.net/rustdoc/sorts

Many of the implementations were done with inspiration from the relevant
Wikipedia articles.

Tests can be run with `make test`. Benchmarks can be run with `make bench`. 
Since they can take a long time to run, here are all benchmarks on my machine.
My specs: Intel i3930K (12 threads) with 32GB of memory. Compiled with `-O`.

Note that sorting algorithms with average case `O(n^2)` or worse complexity are 
not benchmarked on the `medium` and `large` sizes.

The `std` sort is the one from Rust's standard library.
