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 another vector. //! * 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. pub mod permutation; pub use permutation::*;
