The full set of known editions.

Variants

EDITION_UNKNOWN = 0

A placeholder for an unknown edition value.

EDITION_LEGACY = 900

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

EDITION_PROTO2 = 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.

EDITION_PROTO3 = 999

EDITION_2023 = 1_000

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.

EDITION_2024 = 1_001

EDITION_UNSTABLE = 9_999

A placeholder edition for developing and testing unscheduled features.

EDITION_1_TEST_ONLY = 1

Placeholder editions for testing feature resolution. These should not be used or relied on outside of tests.

EDITION_2_TEST_ONLY = 2

EDITION_99997_TEST_ONLY = 99_997

EDITION_99998_TEST_ONLY = 99_998

EDITION_99999_TEST_ONLY = 99_999

EDITION_MAX = 2_147_483_647

Placeholder for specifying unbounded edition support. This should only ever be used by plugins that can expect to never require any changes to support a new edition.

Trait Implementations

impl Clone for Edition

fn clone(&self) -> Edition

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for Edition

impl Debug for Edition

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Edition

fn default() -> Self

Returns the “default value” for a type.

impl Enumeration for Edition

fn from_i32(value: i32) -> Option<Self>

Convert from an i32 wire value to the enum.

fn to_i32(&self) -> i32

Convert the enum to its i32 wire value.

fn proto_name(&self) -> &'static str

The name of this enum variant as it appears in the .proto file.

fn from_proto_name(name: &str) -> Option<Self>

Look up a variant by its protobuf name string.

fn values() -> &'static [Self]

All known variants of this enum, in proto declaration order.

impl Eq for Edition

impl Hash for Edition

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Edition

fn eq(&self, other: &Edition) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
