Struct Loop 

pub struct Loop {
    pub segments: Vec<Segment>,
}

A closed, directed sequence of segments (each ends where the next starts).

Fields

segments: Vec<Segment>

Implementations

impl Loop

pub fn new(segments: Vec<Segment>) -> Self

pub fn polygon(points: &[Point2]) -> Self

A closed polygon through points (last joins back to first).

pub fn rectangle(min: Point2, max: Point2) -> Self

An axis-aligned rectangle, counter-clockwise.

pub fn circle(center: Point2, radius: f64, ccw: bool) -> Self

A full circle as four quadrant arcs, counter-clockwise when ccw.

pub fn stadium(a: Point2, b: Point2, radius: f64) -> Self

A stadium (slot) around the centre line a-b with the given radius, counter-clockwise.

pub fn reversed(&self) -> Self

pub fn signed_area(&self) -> f64

Shoelace area of the chords plus the arc bulges; positive counter-clockwise.

pub fn is_ccw(&self) -> bool

pub fn length(&self) -> f64

pub fn bounds(&self) -> (Point2, Point2)

pub fn discretize(&self, tol: f64) -> Vec<Point2>

Chord points around the loop (first point not repeated at the end).

pub fn winding(&self, p: Point2, tol: &Tolerance) -> i32

Winding number of p about this loop alone.

pub fn validate(&mut self, tol: &Tolerance) -> Result<(), PlanarError>

Closed (consecutive endpoints coincide within point_eps), every segment valid, at least two segments. Snaps consecutive endpoints to the same coordinates.

pub fn canonical(&self, tol: &Tolerance) -> Loop

The loop as canonical pieces (arcs split per quadrant).

Trait Implementations

impl Clone for Loop

fn clone(&self) -> Self

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

Performs copy-assignment from source.

impl Debug for Loop

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

Formats the value using the given formatter.

impl Default for Loop

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Loop

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

where __D: Deserializer<'de>,
