Struct Polygon 

pub struct Polygon {
    pub hull: SmallVec<[Point; 8]>,
    pub holes: Vec<SmallVec<[Point; 8]>>,
}

Fields

hull: SmallVec<[Point; 8]>

holes: Vec<SmallVec<[Point; 8]>>

Implementations

impl Polygon

pub fn rect(b: Bbox) -> Self

pub fn from_hull(hull: impl IntoIterator<Item = Point>) -> Self

Build a polygon from a hull. The hull is canonicalized: clockwise winding, starting from the lowest-y/lowest-x vertex. This matches KLayout’s canonical form so cross-tool round-trips preserve byte-equal vertex sequences.

pub fn from_hull_raw(hull: impl IntoIterator<Item = Point>) -> Self

Like from_hull but skips canonicalization. Use when you specifically need to preserve a particular vertex order (extremely rare; mainly for tests that probe normalization itself).

pub fn normalize(&mut self)

Canonicalize in place: hull → lowest-y/lowest-x first, CW winding; holes → lowest-y/lowest-x first, CCW winding; hole list sorted by the first vertex of each hole so polygons that differ only in hole-construction order hash identically.

pub fn add_hole(&mut self, hole: impl IntoIterator<Item = Point>)

Append a hole, normalizing winding and re-sorting the hole list.

pub fn bbox(&self) -> Bbox

pub fn transform(&self, t: Trans) -> Polygon

Trait Implementations

impl Clone for Polygon

fn clone(&self) -> Polygon

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Polygon

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

Formats the value using the given formatter.

impl From<Polygon> for Shape

fn from(p: Polygon) -> Self

Converts to this type from the input type.

impl Hash for Polygon

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 PartialEq for Polygon

fn eq(&self, other: &Polygon) -> 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.
