value_type_t

template<typename T >

eve::value_type_t

A meta function for getting an associated value_type for a relaxed iterator/range.

Template Parameters

T	Type to process

   If T has begin/end - value_type_t for return type of begin
   If T is std::iterator -> returns iterator_traits<T>::value_type
   If T has nested `value_type` -> returns it
   If T is a product type and all elements have value_type_t defined for them -
      kumi::tuple for the individual product types.
   Otherwise it's undefined.
