Description

This module implements a simple top-down merge sort. The temporary buffer is preallocated to 1/2 the size of the input array, and shared through the entire sorting process to ease the amount of allocation performed in total. This is a stable sort.

Synopsis

- sort :: (PrimMonad m, MVector v e, Ord e) => v (PrimState m) e -> m ()
- sortBy :: (PrimMonad m, MVector v e) => Comparison e -> v (PrimState m) e -> m ()
- type Comparison e = e -> e -> Ordering

# Documentation

sort :: (PrimMonad m, MVector v e, Ord e) => v (PrimState m) e -> m ()

Sorts an array using the default comparison.

sortBy :: (PrimMonad m, MVector v e) => Comparison e -> v (PrimState m) e -> m ()

Sorts an array using a custom comparison.

type Comparison e = e -> e -> Ordering

A type of comparisons between two values of a given type.
