Module model 

Modules

curve_relation

Curve relationships that require graph references.

graph

Immutable geometry DAG and append-only builder.

id

Typed graph identity.

node

Closed set of format-neutral graph node families.

solid_operation

Solid construction relationships and CSG instructions.

station

Stations: positions named by a distance along a basis curve (#241, ADR 0082).

surface_relation

Surface relationships that compose curve and surface nodes.

value

Closed conversions from built-in representations into graph nodes.

wire

The versioned wire format of a GeometryGraph (ADR 0085).

Structs

CurveSegment

One oriented curve in a composite.

CurveStation

A point and frame at a station along a basis curve.

GeometryGraph

Immutable acyclic geometry graph with one or more roots.

GeometryGraphBuilder

Append-only builder that makes cycles and dangling references unrepresentable.

Instance

Reuse one graph node under a transform, preserving instancing.

InstanceAtStation

A node reused in the frame of an OrientedCurveStation (#264): the station-framed form of Instance.

NodeId

Stable index owned by one immutable crate::GeometryGraph.

OpenProfile

Source-authored bounded open two-dimensional profile path.

OrientedCurveStation

A CurveStation with an explicit orientation (#246) and the side of a seam it reads (#263).

PointOnCurve

Point constrained to a curve parameter.

PointOnSurface

Point constrained to surface parameters.

RunStation

A station of an offset run with the side of a seam it reads and its seam-snapping window (#301): the general form of the plain Station a CurveRelation::OffsetByStations takes, used by CurveRelation::OffsetsAtStations. It may also stand at its basis’s start or end, its distance measured by the kernel (#303).

Section

Position of one section along a sectioned sweep.

SectionAtStation

A section standing at a station, with optional tags and an optional explicit orientation (#246): the general form of StationedSection (closed) and StationedOpenSection (open).

Station

A distance along a basis curve with offsets in its section frame.

StationOffsets

Offsets of a station from its basis curve, in the curve’s section frame.

StationOrientation

An explicit in-section orientation at a station (#246).

StationedOpenSection

An open section standing at a station along a sectioned surface’s directrix, its points named by tags.

StationedSection

A closed profile standing at a station along a sectioned spine’s directrix.

SurfaceSides

Which parametric side of a surface curve a p-curve belongs to.

Enums

BasisEnd

Which end of its basis a RunStation stands at, measured by the kernel (#303; see the module documentation).

BooleanOperator

Regularized boolean set operation on solids.

CurveRelation

Relationship between curve nodes.

GeometryNode

One node in an immutable geometry DAG.

GraphError

Invalid graph construction.

MasterRepresentation

Which representation governs a redundant surface-curve definition.

RuledSide

One side of a ruled surface (#402).

SeamSide

The piece a position exactly on a seam is read from.

SolidOperation

Relationship that constructs a solid from lower-level geometry.

StationFrame

Which frame a station’s offsets and orientation are read in.

SurfaceRelation

Relationship between surface nodes.

Transition

Continuity declared between consecutive composite segments.

TrimSelector

One trim selector preserved from a source representation.

TrimmingPreference

Preference when both parameter and Cartesian trim selectors exist.

Constants

ORIENTATION_TOLERANCE

Largest sine of the angle between a StationOrientation’s axis and reference direction that still counts as parallel.

Traits

BuiltInNode

A built-in neutral value that can be inserted into a crate::GeometryGraph.
