Concept definition

template<typename T>
concept idfxx::receivable_event_data =  std::is_trivially_copyable_v<T> || requires(const void* data) {
    { T::from_opaque(data) } -> std::same_as<T>;
}

Detailed Description

Concept for types that can be received as event data.

A type satisfies receivable_event_data if it is trivially copyable (allowing automatic reconstruction via static cast) or provides a static from_opaque(const void*) method for custom reconstruction.

Trivially copyable types satisfy this concept automatically without needing to provide from_opaque. Types that require custom reconstruction (e.g., wrapping C structs into richer C++ types) can provide a static from_opaque method instead.

Template Parameters

T	The type to check.
