Struct Curve 

pub struct Curve<'m> { /* private fields */ }

The geometry under an Edge, or a curve a feature designates. Call Curve::kind to dispatch.

Implementations

impl<'m> Curve<'m>

pub fn key(&self) -> EntityKey

This curve’s global identity (a Copy key for maps / dedup; a curve shared by several edges yields the same key()).

impl<'m> Curve<'m>

pub fn color(&self) -> Option<Rgb>

The colour of this curve’s line style (CURVE_STYLE.curve_colour), if any.

pub fn width(&self) -> Option<f64>

The line width of this curve’s style (CURVE_STYLE.curve_width, a raw measure value), if any.

pub fn line_font(&self) -> Option<&'m str>

The line-font name of this curve’s style (CURVE_STYLE.curve_font, a line pattern like continuous / dashed), if any.

pub fn to_nurbs(&self) -> Option<NurbsCurve>

The rational-B-spline (NurbsCurve) form of this curve, if the kind is supported (circle, ellipse, B-spline with knots). Returns the full analytic curve — trimming applied by an edge that uses this curve is not reflected here. None for a curve that needs bounds it alone lacks — an unbounded line, say; use Edge::to_nurbs there.

pub fn kind(&self) -> CurveKind<'m>

Trait Implementations

impl<'m> Clone for Curve<'m>

fn clone(&self) -> Curve<'m>

Returns a duplicate of the value.

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

Performs copy-assignment from source.
