Struct Annulus

pub struct Annulus {
    pub inner_circle: Circle,
    pub outer_circle: Circle,
}

A primitive shape formed by the region between two circles, also known as a ring.

Fields

inner_circle: Circle

The inner circle of the annulus

outer_circle: Circle

The outer circle of the annulus

Implementations

impl Annulus

pub const fn new(inner_radius: f32, outer_radius: f32) -> Self

Create a new Annulus from the radii of the inner and outer circle

pub fn diameter(&self) -> f32

Get the diameter of the annulus

pub fn thickness(&self) -> f32

Get the thickness of the annulus

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

Finds the point on the annulus that is closest to the given point:

• If the point is outside of the annulus completely, the returned point will be on the outer perimeter.
• If the point is inside of the inner circle (hole) of the annulus, the returned point will be on the inner perimeter.
• Otherwise, the returned point is overlapping the annulus and returned as is.
