Enum gtk4::ConstraintRelation

#[non_exhaustive]
pub enum ConstraintRelation {
    Le,
    Eq,
    Ge,
}

The relation between two terms of a constraint.

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.

Le

Less than, or equal

Eq

Equal

Ge

Greater than, or equal

Trait Implementations

fn clone(&self) -> ConstraintRelation

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ConstraintRelation

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

Formats the value using the given formatter.

impl From<ConstraintRelation> for Value

fn from(v: ConstraintRelation) -> Self

Converts to this type from the input type.

impl<'a> FromValue<'a> for ConstraintRelation

type Checker = GenericValueTypeChecker<ConstraintRelation>

Value type checker.

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

Get the contained value from a Value.

impl HasParamSpec for ConstraintRelation

type ParamSpec = ParamSpecEnum

type SetValue = ConstraintRelation

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

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

fn param_spec_builder() -> Self::BuilderFn

impl Hash for ConstraintRelation

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 ConstraintRelation

fn cmp(&self, other: &ConstraintRelation) -> 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 + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for ConstraintRelation

fn eq(&self, other: &ConstraintRelation) -> 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 PartialOrd for ConstraintRelation

fn partial_cmp(&self, other: &ConstraintRelation) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

This method tests less than (for self and other) and is used by the < operator.

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl StaticType for ConstraintRelation

fn static_type() -> Type

Returns the type identifier of Self.

impl ToValue for ConstraintRelation

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 ConstraintRelation

type Type = ConstraintRelation

Type to get the Type from.

impl Copy for ConstraintRelation

impl Eq for ConstraintRelation

impl StructuralPartialEq for ConstraintRelation
