Crate ifc_lite_landxml 

Bounded, event-driven LandXML 1.0, 1.1, and 1.2 source ingestion.

This crate intentionally stops at durable LandXML semantic records. It neither fabricates IFC nor creates renderer meshes; later adapters own coordinate systems, mesh partitioning, and presentation.

Modules

alignment

LandXML horizontal alignment semantics and deterministic numeric probes.

Structs

LandXmlAlignment

A horizontal alignment that owns profiles and cross-sections by source id.

LandXmlCancellationFlag

Share this flag with a native task and call Self::cancel from its host.

LandXmlCanonicalVertex

One canonical planar vertex used by generated constrained terrain.

LandXmlCapabilities

LandXmlCapabilityDiagnostic

A parser capability gap retained with its source identity and path.

LandXmlCgPoint

A COGO point’s namespace-local identity is distinct from its display name.

LandXmlCoordinateSystem

Source-owned CRS declarations from LandXML 1.2’s root CoordinateSystem. Kept as raw strings: only the viewer adapter may accept explicit EPSG IDs.

LandXmlCrossSection

A sampled cross-section at one station on its parent alignment.

LandXmlCrossSectionPoint

A cross-section point as authored, including its optional source references.

LandXmlCrossSectionSegment

A continuous sampled CrossSectSurf/PntList2D sequence.

LandXmlCrossSectionSurface

One source cross-section surface, never a generated corridor surface.

LandXmlDocument

The durable LandXML source document joins terrain and plan semantics from the same original byte stream. It deliberately does not create IFC or a renderer-specific representation; the canonical loader owns that step.

LandXmlError

Parse failure with a stable code suitable for native/server/wasm mapping.

LandXmlExtension

A non-LandXML namespace root retained for diagnostics and later adapters.

LandXmlGradeLine

A continuous PntList2D segment of a sampled profile.

LandXmlLimits

Hard limits applied before semantic allocations grow with untrusted input.

LandXmlMetadataRecordFragment

Bounded transport fragment for one metadata record value.

LandXmlMetadataStreamAssembler

Reassembles move-owned metadata cursor events for adapters that still need a complete semantic document at their compatibility boundary.

LandXmlMetadataStreamEnd

Counters emitted after every move-owned metadata record.

LandXmlMetadataStreamHeader

Metadata header emitted once, after all surface fragments have received credit. Its record vectors are intentionally empty; their values follow as individually owned LandXmlMetadataStreamEvent::Record values.

LandXmlMonument

A monument retains the source point reference instead of resolving it away.

LandXmlParcel

LandXmlParcelProbe

Measurements remain in the document’s declared coordinate units.

LandXmlPipe

One validated graph edge in a pipe network.

LandXmlPipeConnectivity

A pipe’s graph edge after refStart and refEnd resolve to source nodes.

LandXmlPipeFeature

A schema-valid Feature child retained without assigning IFC meaning.

LandXmlPipeFlow

Preserved flow attributes; the parser does not derive hydraulic results.

LandXmlPipeInvert

The direction-specific invert belonging to a structure and pipe.

LandXmlPipeMeasure

A finite authored measurement and the source unit used to make it useful.

LandXmlPipeNetwork

One exact LandXML PipeNetwork source hierarchy.

LandXmlPipeNetworkCollection

One exact PipeNetworks collection and its authored metadata.

LandXmlPipeNetworkDocument

Pipe-network semantic result. It is intentionally independent from TIN.

LandXmlPipePosition

A coordinate authored directly in a pipe-network Center element.

LandXmlPipeRefusal

A semantic refusal for a single source element, not a fabricated fallback.

LandXmlPipeSourceBatch

Stable source identities prepared for a future canonical LandXML adapter.

LandXmlPipeStructure

One structure in source order, with source-to-pipe invert provenance.

LandXmlPipeUnits

The length units effective for one pipe-network collection.

LandXmlPlanDocument

Durable COGO and plan records joined to the canonical LandXML document.

LandXmlPlanFeature

LandXmlPlanGeometry

An analytic CoordGeom primitive, never a tessellated substitute.

LandXmlPlanLimits

Plan-record bounds layered over the shared hostile-XML limits.

LandXmlPlanPoint

A coordinate in LandXML’s authored northing/easting/elevation order.

LandXmlPlanResolver

One document-scoped resolver used by bulk adapters. Cached failures are as important as points: dangling, ambiguous and cyclic aliases must not be retraversed for every dependent geometry record.

LandXmlPlanSourceBatch

Bounded source identifiers for host-side navigation and batching.

LandXmlPoint

LandXmlPolyline

One preserved source line/ring (boundary, breakline, or contour).

LandXmlPreservedOnlyExtension

A bounded preserved-only corridor or stringline extension root.

LandXmlProfile

A ProfAlign or ProfSurf record under an alignment.

LandXmlProfilePoint

One station/elevation pair authored by PVI or a sampled grade line.

LandXmlRoadway

A roadway’s named source associations; it does not claim corridor geometry.

LandXmlSourceId

Deterministic source identifier; it is not derived from any output mesh.

LandXmlSourcePoint

Coordinates from Surface/SourceData/DataPoints, separate from face ids.

LandXmlStreamHeader

LandXmlStreamMetadata

Complete non-surface semantics finalized from the same event-driven parsers. terrain.surfaces is empty because complete surfaces were already emitted as bounded fragments with stable source identities.

LandXmlStreamSummary

Deliberately not a fake complete document: surface data is drained before finalization and the summary owns only bounded counters and header facts.

LandXmlSurface

LandXmlSurfaceFragment

LandXmlTerrainDiagnostic

Source-preserving diagnostic; a refusal never turns into guessed terrain.

LandXmlTinDocument

LandXmlTinStreamSession

LandXmlUnits

LandXmlVerticalCurve

A vertical curve anchored at its authored point of vertical intersection.

Enums

LandXmlCapabilityDiagnosticCode

Stable capability diagnostics for non-rendering LandXML road semantics.

LandXmlCrossSectionPointDataFormat

The coordinate convention authored by a CrossSectPnt.

LandXmlCrossSectionSurfaceKind

Whether cross-section values are existing/sampled or planned/design values.

LandXmlDiagnosticCode

Stable, machine-readable reason for an ingestion refusal or invalid source.

LandXmlGeometryKind

LandXmlMetadataRecord

One complete top-level LandXML semantic record. A consumer can release the record before requesting the next credited event.

LandXmlMetadataStreamEvent

Resumable metadata events delivered through LandXmlStreamEvent::Metadata.

LandXmlParcelState

Whether a parcel can be probed without inventing a filled boundary.

LandXmlPipeGeometry

A direct point along the declared pipe route.

LandXmlPipePart

The declared cross-section part of a pipe.

LandXmlPlanPointLocation

A plan geometry endpoint is either authored directly or a COGO reference.

LandXmlPreservedOnlyExtensionKind

The source area containing an unsupported preserved-only subtree.

LandXmlProfileEvaluationError

Why a design profile cannot be evaluated at a requested station.

LandXmlProfileKind

LandXML distinguishes proposed vertical geometry from sampled surface data.

LandXmlRenderState

Honest presentation state for one source surface.

LandXmlStreamEvent

LandXmlStructurePart

The declared part of a structure.

LandXmlSurfaceComponent

LandXmlSurfaceKind

Source topology classification declared by a Surface/Definition.

LandXmlTerrainDiagnosticCode

Stable refusal category for optional constrained terrain adaptation.

LandXmlTopologyOrigin

Whether terrain faces came from the producer or the constrained adapter.

LandXmlVersionCapability

Capability selected from the root LandXML namespace and version attribute.

LandXmlVerticalCurveKind

The exact LandXML vertical-curve declaration.

Constants

MAX_LANDXML_STREAM_EVENT_BYTES

Maximum serialized event retained while reserving queue headroom.

MAX_LANDXML_STREAM_INPUT_CHUNK_BYTES

MAX_LANDXML_STREAM_QUEUED_BYTES

MAX_LANDXML_STREAM_QUEUED_EVENTS

Traits

LandXmlCancellation

Cooperative cancellation hook for hosts that run ingestion off-thread.

Functions

classify_landxml_version

Classify a LandXML root by its namespace-selected grammar and declared version provenance. Producers sometimes pair their grammar namespace with another known declaration; retain that declaration and let the caller record an explicit compatibility diagnostic.

parse_landxml_document

Parse all supported LandXML semantic families from one source buffer.

parse_landxml_pipe_networks

Parse exact LandXML 1.2 pipe networks with default resource limits. This native source parser exposes no renderer, WASM, or invented IFC path.

parse_landxml_pipe_networks_with_cancel

Parse exact LandXML 1.2 pipe networks with host limits and cancellation.

parse_landxml_plan

Parse COGO points, monuments, parcels and plan features from LandXML 1.2.

parse_landxml_plan_with_cancel

Parse plan records while bounding work and polling the caller’s cancellation hook.
