Detailed Description

template<std::size_t N>
struct relx::schema::fixed_string< N >

Compile-time string type that can be used as template non-type parameter in C++20.

This implementation allows usage like:

struct Users { static constexpr auto table_name = "users"; relx::schema::column<"id", int> id; relx::schema::column<"name", std::string> name; relx::schema::column<"email", std::string> email; };
