Namespaces
namespace	randlib

Typedefs
using	randlib::DefaultEngine = Xoshiro256pp
	The engine used by default, including by the per-instance engines of the distributions.

Functions
std::uint64_t	randlib::random_seed ()
template<class Engine = DefaultEngine>
Engine	randlib::seed_from (std::seed_seq &sequence)
template<class Engine = DefaultEngine>
std::vector< Engine >	randlib::make_streams (std::uint64_t seed, std::size_t count)
	Engines for parallel simulations, one per thread: consecutive jump() calls for engines that have them (non-overlapping by construction), distinct PCG streams for Pcg32 and Pcg64, and seeds derived with SplitMix64 for any other engine.
