Constants

EDITION_UNKNOWN

Value: 0

A placeholder for an unknown edition value.

Generated from protobuf enum EDITION_UNKNOWN = 0;

EDITION_LEGACY

Value: 900

A placeholder edition for specifying default behaviors before a feature was first introduced. This is effectively an "infinite past".

Generated from protobuf enum EDITION_LEGACY = 900;

EDITION_PROTO2

Value: 998

Legacy syntax "editions". These pre-date editions, but behave much like distinct editions. These can't be used to specify the edition of proto files, but feature definitions must supply proto2/proto3 defaults for backwards compatibility.

Generated from protobuf enum EDITION_PROTO2 = 998;

EDITION_PROTO3

Value: 999

Generated from protobuf enum EDITION_PROTO3 = 999;

EDITION_2023

Value: 1000

Editions that have been released. The specific values are arbitrary and should not be depended on, but they will always be time-ordered for easy comparison.
