Type Alias style::values::specified::svg_path::PathCommand

pub type PathCommand = GenericShapeCommand<CSSFloat, CSSFloat>;

The SVG path command. The fields of these commands are self-explanatory, so we skip the documents. Note: the index of the control points, e.g. control1, control2, are mapping to the control points of the Bézier curve in the spec.

Implementations

impl PathCommand

fn normalize(&self, state: &mut PathTraversalState) -> Self

Create a normalized copy of this PathCommand. Absolute commands will be copied as-is while for relative commands an equivalent absolute command will be returned.

See discussion: https://github.com/w3c/svgwg/issues/321

fn to_css_for_svg<W>(&self, dest: &mut CssWriter<'_, W>) -> Resultwhere W: Write,

The serialization of the svg path.

Trait Implementations

impl<Angle, LengthPercentage> Animate for GenericShapeCommand<Angle, LengthPercentage>where Angle: Animate, LengthPercentage: Animate,

fn animate(&self, other: &Self, procedure: Procedure) -> Result<Self, ()>

Animate a value towards another one, given an animation procedure.

impl<Angle: Clone, LengthPercentage: Clone> Clone for GenericShapeCommand<Angle, LengthPercentage>

fn clone(&self) -> GenericShapeCommand<Angle, LengthPercentage>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<Angle, LengthPercentage> ComputeSquaredDistance for GenericShapeCommand<Angle, LengthPercentage>where Angle: ComputeSquaredDistance, LengthPercentage: ComputeSquaredDistance,

fn compute_squared_distance(&self, other: &Self) -> Result<SquaredDistance, ()>

Computes the squared distance between two animatable values.

impl<Angle: Debug, LengthPercentage: Debug> Debug for GenericShapeCommand<Angle, LengthPercentage>

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

Formats the value using the given formatter.

impl<'de, Angle, LengthPercentage> Deserialize<'de> for GenericShapeCommand<Angle, LengthPercentage>where Angle: Deserialize<'de>, LengthPercentage: Deserialize<'de>,

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<Angle, LengthPercentage> MallocSizeOf for GenericShapeCommand<Angle, LengthPercentage>where Angle: MallocSizeOf, LengthPercentage: MallocSizeOf,

fn size_of(&self, ops: &mut MallocSizeOfOps) -> usize

Measure the heap usage of all descendant heap-allocated structures, but not the space taken up by the value itself.

impl<Angle: PartialEq, LengthPercentage: PartialEq> PartialEq<GenericShapeCommand<Angle, LengthPercentage>> for GenericShapeCommand<Angle, LengthPercentage>

fn eq(&self, other: &GenericShapeCommand<Angle, LengthPercentage>) -> 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<Angle, LengthPercentage> Serialize for GenericShapeCommand<Angle, LengthPercentage>where Angle: Serialize, LengthPercentage: Serialize,

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>where __S: Serializer,
