Enum Edition

#[repr(i32)]
pub enum Edition {
    Unknown = 0,
    Proto2 = 998,
    Proto3 = 999,
    Edition2023 = 1_000,
    Edition1TestOnly = 1,
    Edition2TestOnly = 2,
    Edition99997TestOnly = 99_997,
    Edition99998TestOnly = 99_998,
    Edition99999TestOnly = 99_999,
}

The full set of known editions.

Variants

Unknown = 0

A placeholder for an unknown edition value.

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.

Proto3 = 999

Edition2023 = 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.

Edition1TestOnly = 1

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

Edition2TestOnly = 2

Edition99997TestOnly = 99_997

Edition99998TestOnly = 99_998

Edition99999TestOnly = 99_999

Implementations

impl Edition

pub fn is_valid(value: i32) -> bool

Returns true if value is a variant of Edition.

pub fn from_i32(value: i32) -> Option<Edition>

Converts an i32 to a Edition, or None if value is not a valid variant.

impl Edition

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

String value of the enum field names used in the ProtoBuf definition. The values are not transformed in any way and thus are considered stable (if the ProtoBuf definition does not change) and safe for programmatic use.

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() -> Edition

Returns the “default value” for a type.

impl From<Edition> for i32

fn from(value: Edition) -> i32

Converts to this type from the input type.

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 Ord for Edition

fn cmp(&self, other: &Edition) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

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 PartialOrd for Edition

fn partial_cmp(&self, other: &Edition) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
