Module rand_distr::weighted_alias

This module contains an implementation of alias method for sampling random indices with probabilities proportional to a collection of weights.

Structs

• WeightedAliasIndex
  A distribution using weighted sampling to pick a discretely selected item.

Traits

• AliasableWeight
  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.
