[][src]Module rand::distributions::weighted::alias_method

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

Structs

WeightedIndex

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

Traits

Weight

Trait that must be implemented for weights, that are used with [WeightedIndex]. Currently no guarantees on the correctness of [WeightedIndex] are given for custom implementations of this trait.
