Message formats::parse::Parse	(	const json::Value &	value,

Conversion from formats::json::Value to google::protobuf::Message. Uses the same format as ugrpc::JsonToMessage with its default options.

Works for google::protobuf::Value, google::protobuf::Struct, google::protobuf::ListValue (top-level and nested) as well, converts them without extra objects in JSON representation.

Use as:

auto value = json.As<google::protobuf::Value>();
