Struct Ellipse2d 

pub struct Ellipse2d { /* private fields */ }

An ellipse in the plane, parameterized by eccentric angle.

Implementations

impl Ellipse2d

pub const fn new(ellipse: Ellipse2) -> Self

A full ellipse.

pub const fn ellipse(&self) -> Ellipse2

The underlying ellipse.

pub const fn is_reversed(&self) -> bool

Whether the curve runs backwards along its underlying ellipse.

Part of the curve’s state and not derivable from its ellipse, so anything that has to reproduce this curve exactly (the native format above all) needs to be able to read it.

Trait Implementations

impl Clone for Ellipse2d

fn clone(&self) -> Ellipse2d

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Ellipse2d

impl Curve2d for Ellipse2d

fn domain(&self) -> (f64, f64)

The parameter interval over which the curve is defined.

fn point_at(&self, u: f64, tol: Tolerances) -> OgeomResult<Point2>

The point at u.

fn d1_at(&self, u: f64, tol: Tolerances) -> OgeomResult<Vector2>

The first derivative at u.

fn derivatives_at( &self, u: f64, n: usize, tol: Tolerances, ) -> OgeomResult<Vec<Vector2>>

Derivatives up to order n, with result[0] the point itself.

fn kind(&self) -> CurveKind

What kind of curve this is.

fn is_closed(&self, _tol: Tolerances) -> bool

Whether the curve’s ends meet.

fn is_periodic(&self) -> bool

Whether the curve continues past its domain by repeating.

fn start(&self, tol: Tolerances) -> OgeomResult<Point2>

The start point.

fn end(&self, tol: Tolerances) -> OgeomResult<Point2>

The end point.

impl Debug for Ellipse2d

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

Formats the value using the given formatter.

impl From<Ellipse2d> for PlanarCurve

fn from(c: Ellipse2d) -> Self

Converts to this type from the input type.

impl PartialEq for Ellipse2d

fn eq(&self, other: &Ellipse2d) -> 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.
