Module rand::seq

Sequence-related functionality

This module provides:

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

Also see:

• crate::distributions::WeightedIndex distribution which provides 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).
