I release this proto at R1: message A { optional B user_b = 1; optional C user_c = 2; optional D user_d = 3; }
but if I find some fault with this proto or extend this proto at R2: message A { optional B user_b = 1; optional C user_c = 2; optional E user_d = 3; optional F user_e = 4; } So , I want use R1's proto instance to encode this message on R2' proto instance. Can I get the true value for the same colums (user_b & user_c) value? Thanks.
