std::experimental::ranges::UniformRandomNumberGenerator

Defined in header `<experimental/ranges/random>`
template <class G> concept bool UniformRandomNumberGenerator = Invocable<G&> && UnsignedIntegral<std::result_of_t<G&()>> && requires { { G::min() } -> Same<std::result_of_t<G&()>>&&; { G::max() } -> Same<std::result_of_t<G&()>>&&; };		(ranges TS)

The concept UniformRandomNumberGenerator<G> specifies that G is the type of a uniform random number generator, that is, objects of type G is a function object returning unsigned integer values such that each value in the range of possible results has (ideally) equal probability of being returned.

UniformRandomNumberGenerator<G> is satisfied only if, given any object g of type G:

G::min() and G::max() are prvalue constant expressions;
G::min() < G::max()
g() is in the range [G::min(), G::max()]
g() has amortized constant complexity.
