Struct FeatureSupport

#[non_exhaustive]
pub struct FeatureSupport {
    pub edition_introduced: Edition,
    pub edition_deprecated: Edition,
    pub deprecation_warning: String,
    pub edition_removed: Edition,
    /* private fields */
}

Information about the support window of a feature.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

edition_introduced: Edition

The edition that this feature was first available in. In editions earlier than this one, the default assigned to EDITION_LEGACY will be used, and proto files will not be able to override it.

edition_deprecated: Edition

The edition this feature becomes deprecated in. Using this after this edition may trigger warnings.

deprecation_warning: String

The deprecation warning text if this feature is used after the edition it was marked deprecated in.

edition_removed: Edition

The edition this feature is no longer available in. In editions after this one, the last default assigned will be used, and proto files will not be able to override it.

Implementations

impl FeatureSupport

pub fn new() -> Self

pub fn set_edition_introduced<T: Into<Edition>>(self, v: T) -> Self

Sets the value of edition_introduced.

pub fn set_edition_deprecated<T: Into<Edition>>(self, v: T) -> Self

Sets the value of edition_deprecated.

pub fn set_deprecation_warning<T: Into<String>>(self, v: T) -> Self

Sets the value of deprecation_warning.

pub fn set_edition_removed<T: Into<Edition>>(self, v: T) -> Self

Sets the value of edition_removed.

Trait Implementations

impl Clone for FeatureSupport

fn clone(&self) -> FeatureSupport

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FeatureSupport

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

Formats the value using the given formatter.

impl Default for FeatureSupport

fn default() -> FeatureSupport

Returns the “default value” for a type.

impl Message for FeatureSupport

fn typename() -> &'static str

The typename of this message.

impl PartialEq for FeatureSupport

fn eq(&self, other: &FeatureSupport) -> 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.
