Module rand_distr::weighted_alias
source · [−]Expand description
This module contains an implementation of alias method for sampling random indices with probabilities proportional to a collection of weights.
Structs
A distribution using weighted sampling to pick a discretely selected item.
Traits
Trait that must be implemented for weights, that are used with
WeightedAliasIndex. Currently no guarantees on the correctness of
WeightedAliasIndex are given for custom implementations of this trait.
