Implementations

impl Circle

pub const fn new(radius: f32) -> Circle

Create a new Circle from a radius

pub fn diameter(&self) -> f32

Get the diameter of the circle

pub fn area(&self) -> f32

Get the area of the circle

pub fn perimeter(&self) -> f32

pub fn closest_point(&self, point: Vec2) -> Vec2
