Struct Circle 

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

A circle defined by its centre and radius.

Fields

center: Coordinate

Centre of the circle.

radius: f64

Radius of the circle (always ≥ 0).

Implementations

impl Circle

pub fn contains(&self, p: Coordinate) -> bool

Returns true when p is inside or on the boundary of the circle.

A small epsilon (1e-10) is added to the radius to absorb floating-point rounding that arises during the Welzl recursion.

pub fn zero() -> Self

The degenerate circle at the origin with zero radius.

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 Debug for Circle

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

Formats the value using the given formatter.

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.
