Struct Polyline 

pub struct Polyline {
    pub points: Vec<Point>,
    pub parameters: Vec<f64>,
    pub deflection_met: bool,
}

A curve approximated by points, with the parameters they came from.

The parameters are kept, not discarded, because the pcurve of the same edge on an adjacent face has to be sampled at exactly these values for the two faces to meet.

Fields

points: Vec<Point>

The points, in order along the curve.

parameters: Vec<f64>

The parameter each point came from.

deflection_met: bool

Whether the requested deflection was actually achieved.

false when the segment ceiling was reached first. Reporting it beats silently returning a coarser polyline than asked for, which would make a downstream tolerance claim untrue with nothing to show why.

Implementations

impl Polyline

pub fn segment_count(&self) -> usize

Number of segments.

pub fn length(&self) -> f64

Total length of the polyline.

An underestimate of the curve’s own length, since a chord is shorter than the arc it spans, and one that improves as the deflection tightens.

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

Whether the polyline returns to where it started.

Trait Implementations

impl Clone for Polyline

fn clone(&self) -> Polyline

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Polyline

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

Formats the value using the given formatter.

impl PartialEq for Polyline

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