Enum FeatureStatus 

#[non_exhaustive]
pub enum FeatureStatus {
    Embedder,
    Unstable,
    Internal,
    Developer,
    Testable,
    Preview,
    Stable,
    Mature,
}

Available on crate feature v2_42 only.

Describes the status of a [structFeature].

The status for a given feature can be obtained with [idFeature::status()].

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Embedder

Feature that adjust behaviour for specific application needs. The feature is not part of a Web platform feature, not a mature feature intended to be always on.

Unstable

Feature in development. The feature may be unfinished, and there are no guarantees about its safety and stability.

Internal

Feature for debugging the WebKit engine. The feature is not generally useful for user or web developers, and always disabled by default.

Developer

Feature for web developers. The feature is not generally useful for end users, and always disabled by default.

Testable

Feature in active development and complete enough for testing. The feature may not be yet ready to ship and is disabled by default.

Preview

Feature ready to be tested by users. The feature is disabled by default, but may be enabled by applications automatically e.g. in their “technology preview” or “beta” versions.

Stable

Feature ready for general use. The feature is enabled by default, but it may still be toggled to support debugging and testing.

Mature

Feature in general use. The feature is always enabled and in general there should be no user-facing interface to toggle it.

Trait Implementations

impl Clone for FeatureStatus

fn clone(&self) -> FeatureStatus

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FeatureStatus

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

Formats the value using the given formatter.

impl From<FeatureStatus> for Value

fn from(v: FeatureStatus) -> Self

Converts to this type from the input type.

impl<'a> FromValue<'a> for FeatureStatus

type Checker = GenericValueTypeChecker<FeatureStatus>

Value type checker.

unsafe fn from_value(value: &'a Value) -> Self

Get the contained value from a Value.

impl HasParamSpec for FeatureStatus

type ParamSpec = ParamSpecEnum

type SetValue = FeatureStatus

Preferred value to be used as setter for the associated ParamSpec.

type BuilderFn = fn(&str, FeatureStatus) -> ParamSpecEnumBuilder<'_, FeatureStatus>

fn param_spec_builder() -> Self::BuilderFn

impl Hash for FeatureStatus

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, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for FeatureStatus

fn cmp(&self, other: &FeatureStatus) -> 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 FeatureStatus

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

fn partial_cmp(&self, other: &FeatureStatus) -> 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 StaticType for FeatureStatus

fn static_type() -> Type

Returns the type identifier of Self.

impl ToValue for FeatureStatus

fn to_value(&self) -> Value

Convert a value to a Value.

fn value_type(&self) -> Type

Returns the type identifier of self.

impl ValueType for FeatureStatus

type Type = FeatureStatus

Type to get the Type from.

impl Copy for FeatureStatus

impl Eq for FeatureStatus

impl StructuralPartialEq for FeatureStatus
