常见的想当然
proto.Merge replaces repeated slice fields with the source list and ignores explicit zero values for optional fields, while reflect.DeepEqual can safely compare protobuf messages.
这是本样本作者记下的、开发者或模型在此处通常会有的预期。下面的契约才是真正运行过的东西。
契约
- proto.Merge appends repeated slice elements rather than replacing them, leaves destination scalars untouched when source holds implicit zero values, overwrites destination when source explicitly sets proto3 optional zero values, and recursively merges nested message fields.
- proto.Merge replaces matching map entry values with the source message rather than recursively merging nested submessages within the map.
- proto.Clone creates an isolated deep copy where mutating cloned slices, maps, or nested messages does not affect the original message, and proto.Clone(nil) returns nil.
- proto.Equal correctly evaluates semantic message equality including IEEE 754 NaN == NaN for float/double fields, whereas reflect.DeepEqual fails on NaN and internal message state.
- protoreflect.Message.Has distinguishes between implicit-presence scalars (reporting false for default zero) and proto3 optional scalars (reporting true even when explicitly set to zero).
- proto.Reset clears all message fields in-place back to their default unpopulated state without reallocating the message struct.
