Module rand::seq

Sequence-related functionality

This module provides:

• [seq::SliceRandom] slice sampling and mutation
• [seq::IteratorRandom] iterator sampling
• [seq::index::sample] low-level API to choose multiple indices from 0..length

Also see:

• [distributions::weighted] module which provides implementations of weighted index sampling.

In order to make results reproducible across 32-64 bit architectures, all usize indices are sampled as a u32 where possible (also providing a small performance boost in some cases).
