Crate partial_min_max

min and max functions that work with PartialOrd.

When given NaNs and other values that don't have total orderings, the functions have well-defined (but arbitrary) behavior: return the second argument.

use partial_min_max::{min, max};
use std::f32::NAN;

// Does what you expect for the easy cases...
assert_eq!(min(0.0, 1.0), 0.0);
assert_eq!(max(0.0, 1.0), 1.0);

// In the case of comparisons with NaN or other partial orderings, returns the
// second value.
assert!(min(0.0, NAN).is_nan());
assert_eq!(min(NAN, 0.0), 0.0);

Functions

max	A version of std::cmp::max that works with PartialOrd types.
min	A version of std::cmp::min that works with PartialOrd types.
