microfmt::detail::has_formatter< T, typename > Struct Template Reference

Detects whether formatter<T> has been given a definition (as opposed to just matching the template <typename T, typename Enable = void> struct formatter; forward declaration), using the standard decltype(sizeof(T)) completeness-detection idiom: sizeof of an incomplete type in the immediate context of a partial specialization's template argument substitution is a SFINAE failure, not a hard error.
