The concept UniformRandomNumberGenerator<G> specifies that G is the type of a uniform random number generator, that is, objects of type G

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.
