Public Types

Public Member Functions
template<typename T, typename U>
T	ReadField (int field_number, const U &message_field)
	Converts protobuf message field message_field with number field_number to a proto struct field with type T.
template<proto_structs::traits::ProtoStruct TStruct, proto_structs::traits::ProtoMessage TMessage>
TStruct	ReadField (int field_number, const TMessage &message_field)
	Converts protobuf message field message_field with number field_number to a proto struct field with type T.
template<typename T, typename U>
void	ReadField (T &struct_field, int field_number, const U &message_field)
	Converts protobuf message field message_field with number field_number to the proto struct field struct_field.
bool	HasErrors () const noexcept
	Returns true if context contains at least one error.
void	AddError (int field_number, std::string_view reason)
	Adds conversion error.
void	AddError (const ::google::protobuf::FieldDescriptor &field_desc, std::string_view reason)
	Adds conversion error. Parameter field_desc contains protobuf message field descriptor for which conversion has failed.
void	AddError (std::string_view reason)
	Adds conversion error. Method is intended for cases when it is hard to associate error with concrete field of the protobuf message.
