Struct Rabbit 

pub struct Rabbit {

    pub body_cy: f64,
    pub body_rx: f64,
    pub body_ry: f64,
    pub head_cx: f64,
    pub head_cy: f64,
    pub head_r: f64,
    pub ear_w: f64,
    pub ear_len: f64,
    pub ear_lean: f64,
    pub ear_gap: f64,
    pub eye_dx: f64,
    pub eye_dy: f64,
    pub eye_r: f64,
    pub segments: usize,
}

Parametric knobs for the rabbit silhouette. All in the normalised [-1, 1] design box (y up). Rabbit::default is the tuned mascot; tests and renderers should use it so the geometry is the same everywhere.

Fields

body_cy: f64

Body ellipse centre + radii (the sitting haunch).

body_rx: f64

body_ry: f64

head_cx: f64

Head circle centre + radius (sits above/forward of the body).

head_cy: f64

head_r: f64

ear_w: f64

Ear geometry: half-width at the base, length, lean (x-offset of the tip), and the gap between the two ear centres at the head.

ear_len: f64

ear_lean: f64

ear_gap: f64

eye_dx: f64

Eye dot centre (offset from the head centre) + radius.

eye_dy: f64

eye_r: f64

segments: usize

How many segments to sample each rounded part with (even → symmetric).

Implementations

impl Rabbit

pub fn outline(&self) -> Vec<Loop>

The rabbit as closed polygon loops, outer silhouette first, then the two ears, then the eye dot. Each loop is a CCW ring in the [-1, 1] box (y up). The 2D renderer fills the body+head as the silhouette, fills the ears on top, and punches the eye as a small dark dot.

pub fn silhouette(&self) -> Vec<Loop>

The fillable body silhouette: just the body + head + ears (no eye), the loops a 2D renderer fills as the solid mascot. Returned outer→inner so the renderer can paint them in order (body, head, ears) with one colour.

pub fn eye(&self) -> Loop

The eye dot loop alone (the dark feature drawn on top of the fill).

Trait Implementations

impl Clone for Rabbit

fn clone(&self) -> Rabbit

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Rabbit

impl Debug for Rabbit

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

Formats the value using the given formatter.

impl Default for Rabbit

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for Rabbit

fn eq(&self, other: &Rabbit) -> 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.
