protobuf中的枚舉缺省值應該為ENUN_TYPE_UNSPECIFIED

protobuf中的枚舉缺省值應該為ENUN_TYPE_UNSPECIFIED

(金慶的專欄 2017.11)

Googol 公布的 API Design 規(guī)范中，*.proto 中的枚舉缺省值建議為 ENUN_TYPE_UNSPECIFIED。

The first value should be named ENUM_TYPE_UNSPECIFIED as it is returned when an enum value is not explicitly specified.

enum FooBar {
// The first value represents the default and must be == 0.
FOO_BAR_UNSPECIFIED = 0;
FIRST_VALUE = 1;
SECOND_VALUE = 2;
}

參考：protobuf中的枚舉缺省值應該為UNKNOWN
