Struct ExactBRep

pub struct ExactBRep { /* private fields */ }

Owned, analytic boundary representation.

Every edge and pcurve use has a finite, non-zero native parameter span. An interval is deliberately owned here rather than inferred from endpoints: periodic supports, reversed pcurves, and parameter re-mapping are not recoverable from coordinates. The result may be an open sheet; an eventual exact-solid contract will additionally require a selected closed shell.

Implementations

impl ExactBRep

pub fn face_name(&self, face: FaceId) -> Option<&FaceName>

Persistent structural name for a face, when the producer supplied one.

Absence means the producing operation did not track provenance, not that the face is invalid. Callers that require a name should treat None as a refusal rather than substituting an index.

pub fn edge_name(&self, edge: EdgeId) -> Option<&EdgeName>

Persistent structural name for an edge, when the producer supplied one.

pub fn face_by_name(&self, name: &FaceName) -> Option<FaceId>

Find the face carrying name.

This is the lookup that makes names useful across operations: a caller holding a name from before an edit resolves it against the new result instead of hoping an arena index still points at the same face.

pub fn edge_by_name(&self, name: &EdgeName) -> Option<EdgeId>

Find the edge carrying name.

pub fn name_caps(&mut self, start: Option<FaceName>, end: Option<FaceName>)

Name the two cap faces of a swept solid after assembly.

The caps are identified by construction order – a sweep adds the start cap then the end cap before any wall – rather than by geometry, because a cap that shares a plane with a wall would be ambiguous geometrically. Passing None leaves that cap unnamed.

pub fn topology(&self) -> &BRep<Curve3Id, Curve2Id, SurfaceId>

Structural topology with typed support handles.

pub fn curves3(&self) -> &[Curve3]

Owned exact 3D curve supports.

pub fn curves2(&self) -> &[Curve2]

Owned exact 2D trim-curve supports.

pub fn surfaces(&self) -> &[Surface]

Owned exact support surfaces.

pub fn edge_interval(&self, edge: EdgeId) -> Option<Interval>

Native parameter span oriented from an edge’s start vertex to its end.

pub fn pcurve_interval( &self, loop_id: LoopId, use_index: usize, ) -> Option<Interval>

Native parameter span for an edge use’s pcurve in loop traversal order.

Trait Implementations

impl Clone for ExactBRep

fn clone(&self) -> ExactBRep

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ExactBRep

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

Formats the value using the given formatter.

impl PartialEq for ExactBRep

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