Crate axiolid_overlay

Validated, deterministic planar boolean overlay and offset.

Structs

ArcArrangement

The plane cut by several simple arc rings.

ArcOverlayEvidence

Evidence that the arc path did what it claims.

ArcOverlayResult

The result of an arc-aware boolean.

ArcPolygon

An arc-aware region: one outer boundary and its holes.

ArcRing

A closed boundary whose edges may be arcs.

ArcVertex

One boundary vertex and the bulge of the edge leaving it.

ArrangementEdge

One piece of the subdivision: part of one or more input edges, running between two vertices with no other ring’s boundary crossing it.

ArrangementEdgeUse

One use of a piece in a region boundary.

ArrangementRegion

A region of the subdivision: an outer boundary and its holes.

CircleEvidence

Which points determine the circle and how exact the output is.

EdgeSource

Where a piece of the subdivision came from.

EnclosingCircle

A circle by its centre and radius.

MinimumCircle

The circle and its evidence.

MinimumRectangle

The rectangle and its evidence.

MorphologyBound

How a disc morphology’s result relates to the exact one.

OffsetEvidence

What an offset actually did.

OffsetResult

Result of an offset.

OrientedRectangle

A rectangle by its centre, two unit axes and the half extents along them.

OverlayEvidence

OverlayInput

OverlayResult

Polygon

RectangleEvidence

What the construction did and how exact its output is.

Region

A validated planar region: a normalised set of polygons with holes.

RegionEvidence

What an operation did to produce a region.

Ring

Enums

BoundSide

Which side of the exact disc morphology a region lies on.

CapStyle

How an open stroke terminates.

CircleError

Why no circle was built.

FillRule

JoinStyle

How the outline turns a corner.

MinkowskiError

Why a Minkowski operation was refused.

OverlayError

OverlayOperation

RectangleError

Why no rectangle was built.

VisibilityError

Why no visibility polygon was built.

Functions

arc_edge_radius

Arc radius implied by an edge, or None for a straight edge.

arc_overlay

Boolean of two arc-capable regions.

arc_ring_area

Signed area enclosed by an arc ring.

minimum_area_rectangle

The minimum-area rectangle enclosing points.

minimum_enclosing_circle

The minimum circle enclosing points.

offset_polygons

Offset closed polygons by distance.

overlay

Performs a neutral planar overlay. Output ordering is deterministic: polygons sort by outer-ring lexicographic start, rings are canonicalized CCW/CW.

polygon_area

Net area of a polygon: outer boundary minus its holes.

reverse_arc_ring

Reverse a ring’s orientation, preserving its geometry.

ring_area

Absolute area of a ring.

stroke_polyline

Sweep an open polyline into a closed region of the given width.

total_area

Total net area across a set of polygons.

union_soup

Union a set of individually-valid rings that may overlap each other.

validate_arc_ring

Validate an arc ring against the same contract as crate::Ring, plus the arc-specific degeneracies.
