Struct Edition

pub struct Edition(/* private fields */);

The full set of known editions.

Implementations

impl Edition

pub const EDITION_UNKNOWN: Edition

A placeholder for an unknown edition value.

pub const EDITION_LEGACY: Edition

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

pub const EDITION_PROTO2: Edition

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.

pub const EDITION_PROTO3: Edition

pub const EDITION_2023: Edition

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.

pub const EDITION_2024: Edition

pub const EDITION_1_TEST_ONLY: Edition

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

pub const EDITION_2_TEST_ONLY: Edition

pub const EDITION_99997_TEST_ONLY: Edition

pub const EDITION_99998_TEST_ONLY: Edition

pub const EDITION_99999_TEST_ONLY: Edition

pub const EDITION_MAX: Edition

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.

pub fn value(&self) -> i32

Gets the enum value.

pub fn as_str_name(&self) -> Cow<'static, str>

Gets the enum value as a string.

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

Creates an enum value from the value name.

Trait Implementations

impl Clone for Edition

fn clone(&self) -> Edition

Returns a copy 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 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.
