Struct Polygon 

pub struct Polygon { /* private fields */ }

An ordered planar polygon boundary.

Implementations

impl Polygon

pub const fn new(vertices: Vec<Point2>) -> Polygon

Creates a polygon boundary from ordered vertices.

pub fn vertices(&self) -> &[Point2]

Returns the vertices.

pub fn vertex_count(&self) -> usize

Returns the vertex count.

pub fn is_empty(&self) -> bool

Returns true when there are no vertices.

pub fn twice_signed_area(&self) -> f64

Returns twice the signed area by the shoelace formula.

pub fn area(&self) -> f64

Returns the unsigned polygon area.

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<(), Error>

Formats the value using the given formatter.

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.
