Enum Stability

pub enum Stability {
    Unknown,
    Unstable {
        feature: String,
        deprecated: Option<Version>,
    },
    Stable {
        since: Version,
        deprecated: Option<Version>,
    },
}

Representation of the stability attributes associated with a world, interface, function, or type.

This is added for WebAssembly/component-model#332 where @since and @unstable annotations were added to WIT.

The order of the of enum values is significant since it is used with Ord and PartialOrd

Variants

Unknown

This item does not have either @since or @unstable.

Unstable

@unstable(feature = foo)

This item is explicitly tagged @unstable. A feature name is listed and this item is excluded by default in Resolve unless explicitly enabled.

Fields

feature: String

deprecated: Option<Version>

Stable

@since(version = 1.2.3)

This item is explicitly tagged with @since as stable since the specified version. This may optionally have a feature listed as well.

Fields

since: Version

deprecated: Option<Version>

Implementations

impl Stability

pub fn is_unknown(&self) -> bool

Returns whether this is Stability::Unknown.

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 Default for Stability

fn default() -> Stability

Returns the “default value” for a type.

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 Ord for Stability

fn cmp(&self, other: &Stability) -> 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 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 PartialOrd for Stability

fn partial_cmp(&self, other: &Stability) -> 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.

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.

impl Eq for Stability

impl StructuralPartialEq for Stability
