Struct rustc_attr::builtin::Stability

pub struct Stability {
    pub level: StabilityLevel,
    pub feature: Symbol,
}

Represents the following attributes:

• #[stable]
• #[unstable]

Fields

level: StabilityLevel

feature: Symbol

Implementations

impl Stability

pub fn is_unstable(&self) -> bool

pub fn is_stable(&self) -> bool

Trait Implementations

impl Clone for Stability

fn clone(&self) -> Stability

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Stability

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

Formats the value using the given formatter.

impl<__D: Decoder> Decodable<__D> for Stability

fn decode(__decoder: &mut __D) -> Self

impl<__E: Encoder> Encodable<__E> for Stability

fn encode(&self, __encoder: &mut __E)

impl Hash for Stability

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,

Feeds a slice of this type into the given Hasher.

impl<__CTX> HashStable<__CTX> for Stabilitywhere
    __CTX: HashStableContext,

fn hash_stable(&self, __hcx: &mut __CTX, __hasher: &mut StableHasher)

impl PartialEq<Stability> for Stability

fn eq(&self, other: &Stability) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Copy for Stability

impl Eq for Stability

impl StructuralEq for Stability

impl StructuralPartialEq for Stability

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
