Module random Copy item path Source 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. ContextRandomExt RngId 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.
