Totally Ordered IEEE Float Comparison for Rust

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.

rust use totally_ordered::TotallyOrdered; let mut values : [f64; 4] = [-0.0, 0.0, -1.0, 1.0]; TotallyOrdered::new_slice_mut(&mut values).sort();
