Enum CurveFamily 

pub enum CurveFamily {
    MaurerRose,
    Lissajous,
    Hypotrochoid,
    Superformula,
    Harmonograph,
}

Which parametric curve family a [curve] preset draws; unknown names are rejected at load.

A family is a walk and a fit verdict, not a scene: each variant answers curves::arm, and parametric_curve draws whatever that returns without naming a family itself. n, d and phase are read with a family-specific meaning (the attractor precedent, where a..d mean different things per family).

Variants

MaurerRose

The Maurer rose — sin(n * theta) walked at a fixed angular step.

Lissajous

The Lissajous figure — x = sin(n t + phase), y = sin(d t).

Hypotrochoid

The spirograph: a circle rolling inside (hypotrochoid) or outside (epitrochoid) a fixed one, traced by a pen at pen rolling radii from its centre. The sign of n picks which — positive rolls inside — so one family name covers both.

Superformula

Gielis’ superformula — starfish, flowers, polygons and rounded shells from sym, sharpness, lobe and a d that skews the lobes.

Harmonograph

The damped two-pendulum harmonograph — a Lissajous figure whose amplitude dies away by decay along the trace, so it spirals inward rather than closing.

Implementations

impl CurveFamily

pub const ALL: [CurveFamily; 5]

Every family, in roster order — the closed set, and the list the schema export renders rather than restating.

pub fn from_name(name: &str) -> Option<Self>

Parse a [curve] family name, or None if unknown.

pub fn as_str(self) -> &'static str

The [curve] family name this parses from — from_name’s inverse.

Trait Implementations

impl Clone for CurveFamily

fn clone(&self) -> CurveFamily

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CurveFamily

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

Formats the value using the given formatter.

impl PartialEq for CurveFamily

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