ConstexprForEnum()

template<auto First, auto Last, class F >

constexpr void ConstexprForEnum ( F &&  f )

constexpr

Compile-time iteration of sequential enum values from First to Last, inclusive. The given function is called once on each iteration, with the current enum value as an argument.

EnumRange()

template<typename EnumType >

EnumRangeT<EnumType> EnumRange	(	EnumType	begin,
		EnumType	one_past_end
	)

Generate a continuous range of an enum for range-for expressions

convenience function to deduce the right type for instantiating EnumRangeT. See EnumRangeT for more detailed documentation and caveats.

Typical use:

enum class EnumType {
  blue, red, yellow, green, pink
};
for (auto enumvalue : EnumRange(EnumType::red,EnumType::green)) {
  do_stuff(enumvalue); // will be called twice, with arguments red and yellow
}
