Struct Stability 

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

Stability information for an item.

In Item::stability, this refers to regular item stability: whether the item is stable or unstable as represented by the #[stable] or #[unstable] attributes. In Item::const_stability, this refers to using the item in const contexts, as represented by #[rustc_const_stable] or #[rustc_const_unstable].

Fields

feature: String

The feature associated with this stability record.

For unstable items, this is the feature gate associated with the item. For stable items, this is the historical label recorded when the item was stabilized.

level: StabilityLevel

Trait Implementations

impl Clone for Stability

fn clone(&self) -> Stability

Returns a duplicate 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<'de> Deserialize<'de> for Stability

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for Stability

impl PartialEq for Stability

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
