Enum RelationKind

#[non_exhaustive]
pub enum RelationKind {
    Unknown,
    Requires,
    Recommends,
    Supports,
}

Type of a component’s relation to other items.

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.

Unknown

Unknown kind

Requires

The referenced item is required by the component

Recommends

The referenced item is recommended

Supports

The referenced item is supported

Performs copy-assignment from source.

impl Debug for RelationKind

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

Formats the value using the given formatter.

impl From<RelationKind> for Value

fn from(v: RelationKind) -> Self

Converts to this type from the input type.

impl<'a> FromValue<'a> for RelationKind

type Checker = GenericValueTypeChecker<RelationKind>

Value type checker.

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

Get the contained value from a Value.

impl HasParamSpec for RelationKind

type ParamSpec = ParamSpecEnum

type SetValue = RelationKind

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

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

fn param_spec_builder() -> Self::BuilderFn

impl Hash for RelationKind

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 RelationKind

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

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

fn partial_cmp(&self, other: &RelationKind) -> 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 RelationKind

fn static_type() -> Type

Returns the type identifier of Self.

impl ToValue for RelationKind

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 RelationKind

type Type = RelationKind

Type to get the Type from.

impl Copy for RelationKind

impl Eq for RelationKind
