Struct Circle2d 

pub struct Circle2d { /* private fields */ }

A circle in the plane, parameterized by angle.

Implementations

impl Circle2d

pub const fn new(circle: Circle2) -> Self

A full circle.

pub const fn circle(&self) -> Circle2

The underlying circle.

pub const fn is_reversed(&self) -> bool

Whether the curve runs backwards along its underlying circle.

Part of the curve’s state and not derivable from its circle, 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 Circle2d

fn clone(&self) -> Circle2d

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Circle2d

impl Curve2d for Circle2d

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 Circle2d

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

Formats the value using the given formatter.

impl From<Circle2d> for PlanarCurve

fn from(c: Circle2d) -> Self

Converts to this type from the input type.

impl PartialEq for Circle2d

fn eq(&self, other: &Circle2d) -> 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.
