Module seq

Sequence-related functionality

This module provides:

• IndexedRandom for sampling slices and other indexable lists
• IndexedMutRandom for sampling slices and other mutably indexable lists
• SliceRandom for mutating slices
• IteratorRandom for sampling iterators
• index::sample low-level API to choose multiple indices from 0..length

Also see:

• crate::distr::weighted::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).

Re-exports

pub use crate::distr::weighted::Error as WeightError;alloc
