Sorting algorithms implemented in Rust.
- Add this dependency and please consider it's version into your Cargo.toml:
[dependencies]
sorting_rs = "1.2.0"
- Use available sorting algorithms in your Rust code:
use sorting_rs::*;
- API for every sorting function is pretty the same: you just have to pass
mutable reference:
&mut [T]
, orvec![T, T, T, ...]
.T
should havePartialOrd
trait, sometimes you may needCopy
orClone
traits, though all implementations try to avoid this kind of additional requirements. - For more information about origin of algorithms and implementation details, please read modules documentation. Wikipedia is nice starting point too.
