Concept definition

template<typename T>
concept wpi::MutableProtobufSerializable = 
    ProtobufSerializable<T> &&
    requires(T* out, wpi::ProtoInputStream<T>& istream) {
      {
        Protobuf<typename std::remove_cvref_t<T>>::UnpackInto(out, istream)
      } -> std::same_as<bool>;
    }

Detailed Description

Specifies that a type is capable of in-place protobuf deserialization.

In addition to meeting ProtobufSerializable, implementations must define a wpi::Protobuf<T> static member

• bool UnpackInto(T*, wpi::ProtoInputStream<T>&)` to update the pointed-to T with the contents of the message.
