ord_subset Build Status

Crate for working with the Ord subset of certain types like f32, f64.

Documentation is up at https://docs.rs/ord_subset/.

Usage

Add this to your Cargo.toml:

[dependencies]
ord_subset = "3"
extern crate ord_subset;
use ord_subset::{OrdSubsetIterExt, OrdSubsetSliceExt};

fn main() {
  // Slices. Works on vector, too.
  let mut s = [5.0, std::f64::NAN, 3.0, 2.0];
  s.ord_subset_sort();
  assert_eq!(&s[0..3], &[2.0, 3.0, 5.0]);
  assert_eq!(s.ord_subset_binary_search(&5.0), Ok(2));

  // iterators
  assert_eq!( s.iter().ord_subset_max(), Some(&5.0) );
  assert_eq!( s.iter().ord_subset_min(), Some(&2.0) );
}
