Crate totally_ordered[−][src]
Expand description
This crate adds the TotallyOrderable
trait for f32
and f64
values as well as the ABI-transparent TotallyOrdered
type which adds Ord + Eq + Hash
to wrapped floating point values.
Main use case: sorting of floating-point arrays which may or may not contain not-a-numbers, infinities, and positive or negative zeros.
use totally_ordered::TotallyOrdered;
let mut values : [f64; 4] = [-0.0, 0.0, -1.0, 1.0];
TotallyOrdered::new_slice_mut(&mut values).sort();
Structs
An ABI-transparent newtype wrapper around types that adds Ord + Eq to TotallyOrderable types (f32 and f64).
Traits
Implement this for types that are not directly Ord + Eq
, but
can be transformed in place in such a way that the associated
type Transformed
is. Implemented for f32
and f64
.
Implement this for types that are not directly Ord + Eq
, but
can be at a slightly higher runtime cost. Implemented for f32
and f64
.
Functions
(Potentially) faster alternative to TotallyOrdered::new_slice_mut
followed by
sort
for values that can be transformed in place.
