Enum DeprecatedSince 

pub enum DeprecatedSince {
    RustcVersion(RustcVersion),
    Future,
    NonStandard(Ustr),
    Unspecified,
    Err,
}

Release in which an API is deprecated.

Variants

RustcVersion(RustcVersion)

Future

Deprecated in the future (“to be determined”).

NonStandard(Ustr)

feature(staged_api) is off. Deprecation versions outside the standard library are allowed to be arbitrary strings, for better or worse.

Unspecified

Deprecation version is unspecified but optional.

Err

Failed to parse a deprecation version, or the deprecation version is unspecified and required. An error has already been emitted.

Trait Implementations

impl Clone for DeprecatedSince

fn clone(&self) -> DeprecatedSince

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DeprecatedSince

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for DeprecatedSince

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<'s, V> Drive<'s, V> for DeprecatedSince

where V: Visitor + Visit<'s, RustcVersion> + Visit<'s, Ustr>,

fn drive_inner(&'s self, visitor: &mut V) -> ControlFlow<V::Break>

Call v.visit() on the immediate contents of self.

impl<'s, V> DriveMut<'s, V> for DeprecatedSince

where V: Visitor + VisitMut<'s, RustcVersion> + VisitMut<'s, Ustr>,

fn drive_inner_mut(&'s mut self, visitor: &mut V) -> ControlFlow<V::Break>

Call v.visit() on the immediate contents of self.

impl PartialEq for DeprecatedSince

fn eq(&self, other: &DeprecatedSince) -> 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 DeprecatedSince

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
