Module random

Macros§

define_rng: Use this to define a unique type which will be used as a key to retrieve an independent rng instance when calling Context::get_rng.

count_and_sample_single_l_reservoir: Count elements and sample one element uniformly from an iterator of unknown length.
sample_multiple_from_known_length: Samples requested elements uniformly at random without replacement from an iterator whose length is known at runtime. Requires len >= requested.
sample_multiple_l_reservoir: Sample multiple random elements uniformly without replacement from a container of unknown length. If more samples are requested than are in the set, the function returns as many items as it can.
sample_single_from_known_length: Samples one element uniformly at random from an iterator whose length is known at runtime.
sample_single_l_reservoir: Sample a random element uniformly from an iterator of unknown length.
