Module cap_rand::seq::index

Low-level API for sampling indices

Enums

IndexVec	A vector of indices.
IndexVecIntoIter	Return type of IndexVec::into_iter.
IndexVecIter	Return type of IndexVec::iter.

Functions

sample	Randomly sample exactly amount distinct indices from 0..length, and return them in random order (fully shuffled).
sample_weighted	Randomly sample exactly amount distinct indices from 0..length, and return them in an arbitrary order (there is no guarantee of shuffling or ordering). The weights are to be provided by the input function weights, which will be called once for each index.
