Struct ordered_float::OrderedFloat

#[repr(transparent)]
pub struct OrderedFloat<T>(pub T);

A wrapper around floats providing implementations of Eq, Ord, and Hash.

NaN is sorted as greater than all other values and equal to itself, in contradiction with the IEEE standard.

use ordered_float::OrderedFloat;
use std::f32::NAN;

let mut v = [OrderedFloat(NAN), OrderedFloat(2.0), OrderedFloat(1.0)];
v.sort();
assert_eq!(v, [OrderedFloat(1.0), OrderedFloat(2.0), OrderedFloat(NAN)]);

Because OrderedFloat implements Ord and Eq, it can be used as a key in a HashSet, HashMap, BTreeMap, or BTreeSet (unlike the primitive f32 or f64 types):

let mut s: HashSet<OrderedFloat<f32>> = HashSet::new();
s.insert(OrderedFloat(NAN));
assert!(s.contains(&OrderedFloat(NAN)));
