Module rand::seq

source · [−]

Expand description

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).
