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`.

sample	Randomly sample exactly `amount` distinct indices from `0..length`, and return them in random order (fully shuffled).
sample_weighted	`std` 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.
