Concept definition

template<typename T, typename... I>
concept wpi::HasNestedStruct = 
    StructSerializable<T, I...> &&
    requires(function_ref<void(std::string_view, std::string_view)> fn,
             const I&... info) {
      Struct<typename std::remove_cvref_t<T>,
             typename std::remove_cvref_t<I>...>::ForEachNested(fn, info...);
    }

Detailed Description

Specifies that a struct type has nested struct declarations.

In addition to meeting StructSerializable, implementations must define a wpi::Struct<T> static member void ForEachNested(std::invocable<std::string_view, std::string_view) auto fn) (or equivalent) and call ForEachStructSchema<Type> on each nested struct type.
