Enum gsk4::PathOperation

#[non_exhaustive]
pub enum PathOperation {
    Move,
    Close,
    Line,
    Quad,
    Cubic,
    Conic,
}

Available on crate feature v4_14 only.

Path operations are used to describe the segments of a Path.

More values may be added in the future.

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.

Move

A move-to operation, with 1 point describing the target point.

Close

A close operation ending the current contour with a line back to the starting point. Two points describe the start and end of the line.

Line

A line-to operation, with 2 points describing the start and end point of a straight line.

Quad

A curve-to operation describing a quadratic Bézier curve with 3 points describing the start point, the control point and the end point of the curve.

Cubic

A curve-to operation describing a cubic Bézier curve with 4 points describing the start point, the two control points and the end point of the curve.

Conic

A rational quadratic Bézier curve with 3 points describing the start point, control point and end point of the curve. A weight for the curve will be passed, too.

Trait Implementations

impl Clone for PathOperation

fn clone(&self) -> PathOperation

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PathOperation

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

Formats the value using the given formatter.

impl From<PathOperation> for Value

fn from(v: PathOperation) -> Self

Converts to this type from the input type.

impl<'a> FromValue<'a> for PathOperation

type Checker = GenericValueTypeChecker<PathOperation>

Value type checker.

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

Get the contained value from a Value.

impl HasParamSpec for PathOperation

type ParamSpec = ParamSpecEnum

type SetValue = PathOperation

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

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

fn param_spec_builder() -> Self::BuilderFn

impl Hash for PathOperation

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 PathOperation

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

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

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

fn static_type() -> Type

Returns the type identifier of Self.

impl ToValue for PathOperation

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 PathOperation

type Type = PathOperation

Type to get the Type from.

impl Copy for PathOperation

impl Eq for PathOperation

impl StructuralPartialEq for PathOperation
