Struct Circle 

pub struct Circle {
    pub center: Point,
    pub radius: f64,
}

A full circle.

Fields

center: Point

Center.

radius: f64

Radius (> 0 for a valid circle).

Implementations

impl Circle

pub fn new(center: Point, radius: f64) -> GeoResult<Self>

Create a validated circle.

pub fn point_at_angle(self, a: f64) -> Point

Point at angle a (radians).

pub fn length(self) -> f64

Circumference.

pub fn bbox(self) -> Aabb

Bounding box.

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

Closest point on the circle; the center maps to angle 0.

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

Distance from p to the circle line.

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

Apply a transform; only similarities keep a circle a circle.

Trait Implementations

impl Clone for Circle

fn clone(&self) -> Circle

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Circle

impl Debug for Circle

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Circle

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Circle

fn eq(&self, other: &Circle) -> 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 Circle

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
