Implementations

impl Polygon

impl Polygon

Returns the furthest corner point to the center

pub fn is_convex(&self) -> bool

Returns true if any sides point inwards

impl Polygon

pub fn as_inner_circle(&self) -> Circle

Creates a circle using the point closest to the center

pub fn as_outer_circle(&self) -> Circle

Creates a circle using the point farthest to the center

pub fn as_avg_circle(&self) -> Circle

Creates a circle using the average point distance from the center

pub fn as_circle(&self) -> Option<Circle>

Returns

fn intersects_shape(&self, other: &(dyn Shape + 'static)) -> Option<bool>

Returns

impl IntersectsShape for Polygon

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.

impl Serialize for Polygon

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Shape for Polygon

fn rebuild(&self, points: &[Coord]) -> Polygon

where Polygon: Sized,

Used internally

fn contains(&self, point: Coord) -> bool

fn points(&self) -> Vec<Coord>

Points(corners/ends) the shape is made of

fn center(&self) -> Coord

Center of shape

fn outline_pixels(&self) -> Vec<Coord>

The coords for drawing the shape outline, the points may be in any order This should be cached rather than called per frame

fn filled_pixels(&self) -> Vec<Coord>
