`xieite::repeat()`

Defined in header <xieite/fn/repeat.hpp>

Repeatedly calls a functor some constant number of times.
Passes indices to the given functor as an individual template argument.

Declarations

template<std::integral auto n>
constexpr void repeat(auto&& fn, auto&&... args)
	XIEITE_ARROW_RET(/*
		fn.template operator()<0>(args...),
		fn.template operator()<1>(args...),
		fn.template operator()<???>(args...),
		fn.template operator()<(n - 1)>(args...)
	*/)

Repeats for some constant integer.

#1

template<typename... Ts>
constexpr void repeat(auto&& fn, auto&&... args)
	XIEITE_ARROW_RET(xieite::repeat<sizeof...(Ts)>(XIEITE_FWD(fn), XIEITE_FWD(args)...))

Repeats for the number of types passed.

Example

	xieite::repeat<5>([]<int i> static {
		xieite::dump(i);
	});
