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).

Modules

• indexalloc
  Low-level API for sampling indices

Structs

• SliceChooseIteralloc
  An iterator over multiple slice elements.

Traits

• IteratorRandom
  Extension trait on iterators, providing random sampling methods.
• SliceRandom
  Extension trait on slices, providing random mutation and sampling methods.
