Why a profile is not valid as the exact path would build it.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

NotLowered(GeomError)

The profile does not lower to a contour (family or dimensions); nothing else was checked.

TooFewSegments

The segments lower to fewer than two ring vertices (a polyline or a full circle is a whole ring by itself); count is the segments.

Fields

contour: ContourRef

count: usize

UnsupportedSegment

A segment family the exact lowering refuses (ellipse, B-spline, …), or an arc of more than a whole turn: kind names it.

Fields

contour: ContourRef

segment: usize

kind: &'static str

DegenerateSegment

Degenerate frame or empty parameter range.

Fields

contour: ContourRef

segment: usize

reason: &'static str

Gap

The end of segment and the start of the next ((segment + 1) % n, so n - 1 is the closing joint) are gap apart, beyond the slack.

Fields

contour: ContourRef

segment: usize

gap: f64

DegenerateRing

A validate_arc_ring refusal of the lowered ring.

Fields

contour: ContourRef

error: OverlayError

SelfContact

Two segments of one contour share a point other than the joint between consecutive ones. segments are segment indices, ascending; both name one segment when a single arc touches itself. at is the first such point, rounded once.

Fields

contour: ContourRef

segments: [usize; 2]

at: DVec2

BoundaryOverlap

Two contours share a stretch of boundary. contours ascending.

Fields

contours: [ContourRef; 2]

HoleOutsideOuter

Part of a hole lies outside the outer contour.

Fields

hole: usize

DisconnectedInterior

Contacts between contours cut the interior into separate pieces. contours ascending, every contour of the cut component.

Fields

contours: Vec<ContourRef>

Polygon(ArcPolygonDefect)

A defect of the arc polygon check this version does not map to a finding of its own, such as NestingUndecided: nesting could not be decided, so the profile is not valid.

HolesOverlap

Two holes’ interiors meet. holes ascending.

Fields

holes: [usize; 2]

Clearance

Two segments are closer than the requested clearance (ExactProfileValidator::validate_with): their distance has a local minimum strictly between zero and it away from their meeting points, or they form an exact cusp (they meet and leave in the same direction). The neighbourhood of a meeting point at a nonzero angle (a narrow wedge) is not reported. segments are (contour, segment) pairs, ascending. lower_bound is a certified lower bound on their distance; undecided is false when the exact test proved the distance is below the clearance and true when it could not decide and the pair is reported rather than cleared.

Fields

segments: [(ContourRef, usize); 2]

lower_bound: f64

undecided: bool
