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

Trait Implementations

impl Animate for PathCommand

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

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

impl Clone for PathCommand

fn clone(&self) -> PathCommand

Returns a copy of the value.

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

Performs copy-assignment from source.

impl ComputeSquaredDistance for PathCommand

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

Computes the squared distance between two animatable values.

impl Debug for PathCommand

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for PathCommand

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

Deserialize this value from the given Serde deserializer.

impl MallocSizeOf for PathCommand

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 PartialEq<PathCommand> for PathCommand

fn eq(&self, other: &PathCommand) -> 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 Serialize for PathCommand

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

Serialize this value into the given Serde serializer.

impl SpecifiedValueInfo for PathCommand

const SUPPORTED_TYPES: u8 = 0u8

Supported CssTypes by the given value type.

fn collect_completion_keywords(_f: &mut dyn FnMut(&[&'static str]))

Collect value starting words for the given specified value type. This includes keyword and function names which can appear at the beginning of a value of this type.

impl ToAnimatedZero for PathCommand

fn to_animated_zero(&self) -> Result<Self, ()>

Returns a value that, when added with an underlying value, will produce the underlying value. This is used for SMIL animation’s “by-animation” where SMIL first interpolates from the zero value to the ‘by’ value, and then adds the result to the underlying value.

impl ToComputedValue for PathCommandwhere CoordPair: ToComputedValue<ComputedValue = CoordPair>, IsAbsolute: ToComputedValue<ComputedValue = IsAbsolute>, CSSFloat: ToComputedValue<ComputedValue = CSSFloat>, ArcFlag: ToComputedValue<ComputedValue = ArcFlag>,

type ComputedValue = PathCommand

The computed value type we’re going to be converted to.

fn from_computed_value(from: &Self::ComputedValue) -> Self

Convert a computed value to specified value form.

fn to_computed_value(&self, context: &Context<'_>) -> Self::ComputedValue

Convert a specified value to a computed value, using itself and the data inside the Context.

impl ToCss for PathCommand

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

Serialize self in CSS syntax, writing to dest.

fn to_css_string(&self) -> String

Serialize self in CSS syntax and return a string.

impl ToResolvedValue for PathCommandwhere CoordPair: ToResolvedValue<ResolvedValue = CoordPair>, IsAbsolute: ToResolvedValue<ResolvedValue = IsAbsolute>, CSSFloat: ToResolvedValue<ResolvedValue = CSSFloat>, ArcFlag: ToResolvedValue<ResolvedValue = ArcFlag>,

type ResolvedValue = PathCommand

The resolved value type we’re going to be converted to.

fn from_resolved_value(from: Self::ResolvedValue) -> Self

Convert a resolved value to resolved value form.

fn to_resolved_value(self, context: &Context<'_>) -> Self::ResolvedValue

Convert a resolved value to a resolved value.

impl ToShmem for PathCommand

fn to_shmem(&self, builder: &mut SharedMemoryBuilder) -> Result<Self>

Clones this value into a form suitable for writing into a SharedMemoryBuilder.

impl Copy for PathCommand

impl StructuralPartialEq for PathCommand
