Functions
template<typename T>
auto	threadschedule::when_all (std::vector< std::future< T > > &futures) -> std::vector< T >
	Block until all futures complete, returning results in submission order.
void	threadschedule::when_all (std::vector< std::future< void > > &futures)
	Block until all void futures complete.
template<typename T>
auto	threadschedule::when_all_settled (std::vector< std::future< T > > &futures) -> std::vector< expected< T, std::exception_ptr > >
	Block until all futures complete, returning an expected per slot.
auto	threadschedule::when_all_settled (std::vector< std::future< void > > &futures) -> std::vector< expected< void, std::exception_ptr > >
	Block until all void futures complete, returning an expected per slot.
template<typename T>
auto	threadschedule::when_any (std::vector< std::future< T > > &futures) -> std::pair< size_t, T >
	Block until the first future becomes ready.
auto	threadschedule::when_any (std::vector< std::future< void > > &futures) -> size_t
	Block until the first void future becomes ready.

Detailed Description

Combinators for std::future: when_all, when_any, when_all_settled.

These utilities simplify waiting on multiple futures produced by thread pool submissions.
