Performs stream input and output operations on pseudo-random number distribution d.
Traitstemplate parameters, otherwise the behavior is undefined. If bad input is encountered, ist.setstate(std::ios::failbit) is called, which may throw std::ios_base::failure. d is unchanged in that case.
These function templates are not visible to ordinary unqualified or qualified lookup, and can only be found by argument-dependent lookup when
std::bernoulli_distribution is an associated class of the arguments.
