Concept definition

template<typename K>
concept RawModelKey =
    (std::integral<K> && !std::same_as<std::remove_cv_t<K>, bool>) || std::same_as<std::remove_cv_t<K>, std::string>

Detailed Description

Key types that are themselves a wire-encodable scalar.

Restricted to integral types and std::string because a key must round-trip losslessly through the wire's string encoding and be usable as a map key. bool is excluded: it carries one bit of identity, which is never a meaningful primary key and is far more likely to be a mistake.
