Detailed Description

template<typename option_t>
struct seqan3::detail::adl_only::enumeration_names_fn< option_t >

Functor definition for seqan3::enumeration_names.

We need a class template here because we need the original option_t next to s_option_t that may be wrapped std::type_identity to be default constructible. We need option_t to be default constructible because the respective CPO should be callable without a function parameter.
