The full set of known editions.

Working with unknown values

This enum is defined as #[non_exhaustive] because Google Cloud may add additional enum variants at any time. Adding new variants is not considered a breaking change. Applications should write their code in anticipation of:

• New values appearing in future releases of the client library, and
• New values received dynamically, without application changes.

Please consult the Working with enums section in the user guide for some guidelines.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Unknown

A placeholder for an unknown edition value.

Legacy

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

Proto2

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.

Proto3

Edition2023

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.

Edition2024

Edition1TestOnly

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

Edition2TestOnly

Edition99997TestOnly

Edition99998TestOnly

Edition99999TestOnly

Max

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.

UnknownValue(UnknownValue)

If set, the enum was initialized with an unknown value.

Applications can examine the value using Edition::value or Edition::name.

Implementations

impl Edition

pub fn value(&self) -> Option<i32>

Gets the enum value.

Returns None if the enum contains an unknown value deserialized from the string representation of enums.

pub fn name(&self) -> Option<&str>

Gets the enum value as a string.

Returns None if the enum contains an unknown value deserialized from the integer representation of enums.

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 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<'de> Deserialize<'de> for Edition

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Edition

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

Formats the value using the given formatter.

impl From<&str> for Edition

fn from(value: &str) -> Self

Converts to this type from the input type.

impl From<i32> for Edition

fn from(value: i32) -> Self

Converts to this type from the input type.

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.

impl Serialize for Edition

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.

impl StructuralPartialEq for Edition
