Crate permutation [−] [src]
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.
