Concept definition

    template<typename Arg, typename Param>
    concept requirement_for = requires {
        {
            detail::make_arg_matcher<Param>(detail::maxMakeArgMatcherTag, std::declval<Arg>())
        } -> matcher_for<Param>;
    }

Detailed Description

Determines whether Arg can be used as a requirement for Param.

This concept verifies that the given Arg specifies actual requirements for Param. In fact, it does check whether:

• Arg already is an actual matcher for Param (via matcher_for concept),
• Arg and Params are compatible strings (which then utilizes matches::str::eq),
• or Arg and Params are already equality-comparable (which then uses matches::eq).
