std::uniform_random_bit_generator - cppreference.com (original) (raw)

The concept uniform_random_bit_generator<G> specifies that G is the type of a uniform random bit 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.

[edit] Semantic requirements

uniform_random_bit_generator<G> is modeled only if, given any object g of type G:

• g() is in the range [G::min(), G::max()],
• g() has amortized constant complexity.

[edit] Notes

In order to satisfy the requirement std::bool_constant<(G::min() < G::max())>::value, both G::min() and G::max() must be constant expressions, and the result of the comparison must be true.
