Implementations

impl Shape

pub const fn kind(&self) -> ShapeKind

Kind of the shape.

pub fn validate(&self) -> GeoResult<()>

Validate numeric sanity and structural rules.

pub fn curves(&self) -> Vec<Curve>

Decompose into curve pieces. Points and text have none.

pub fn bbox(&self) -> Aabb

Bounding box (text: its layout box with the default font).

pub fn is_region(&self) -> bool

Whether the shape bounds an area (fill and inside tests apply).

pub fn distance_to(&self, p: Point) -> f64

Distance from p to the outline (text: to its layout box).

pub fn contains_point(&self, p: Point, tol: FlattenTolerance) -> bool

Even-odd inside test for regions (always false for non-regions). Straight edges use exact orientation predicates; curved edges are flattened with tol.

pub fn hit(&self, p: Point, radius: f64, fill: bool) -> bool

Hit test: within radius of the outline, or inside when fill is set.

pub fn inside_rect(&self, r: Aabb) -> bool

Window selection: shape entirely inside r.

pub fn intersects_rect(&self, r: Aabb, tol: ModelTolerance) -> bool

Crossing selection: any part of the shape touches r (regions: also when r lies inside the region).

pub fn flatten(&self, tol: FlattenTolerance) -> Vec<FlatPath>

Flatten into polylines/rings with maximum deviation tol.

pub fn anchors(&self) -> Vec<Anchor>

Semantic anchors.

pub fn anchor(&self, name: &str) -> Option<Point>

Anchor by name.

pub fn length(&self) -> f64

Total outline length (text and points: 0).

pub fn area(&self) -> f64

Unsigned area of regions (0 for non-regions). Bézier areas use flattening.

pub fn transform(&self, t: Affine, policy: TransformPolicy) -> GeoResult<Self>

Transform the shape. See TransformPolicy.

Trait Implementations

impl Clone for Shape

fn clone(&self) -> Shape

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Shape

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Shape

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Shape

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
