# Rust Permutations
Permutations is a rust library for manipulating and applying permutations.
//! A module for representing permutations, applying them to slices and indices,
//! and computing them from sort orders.
//!
//! Some practical uses of this module are:
//! * Calculate a sort, and apply it later.
//! * Calculate a sort on one vector, and apply it to multiple other vectors.
//! * Calculate the new index of an element before sorting.
//! * Remember the prior index of an element after sorting.
//! * Undo a sort.
//! * Compare the orderings of elements.
