Struct BooleanClippingProcessor 

pub struct BooleanClippingProcessor { /* private fields */ }

BooleanResult processor Handles IfcBooleanResult and IfcBooleanClippingResult - CSG operations

Supports all IFC boolean operations:

• DIFFERENCE: Subtracts second operand from first (wall clipped by roof, openings, etc.)
  • Uses efficient plane clipping for IfcHalfSpaceSolid operands
  • Uses full 3D CSG for solid-solid operations (e.g., roof/slab clipping)
• UNION: Combines two solids into one
• INTERSECTION: Returns the overlapping volume of two solids

Performance notes:

• HalfSpaceSolid clipping is very fast (simple plane-based triangle clipping)
• Solid-solid CSG only invoked when actually needed (no overhead for simple geometry)
• Graceful fallback to first operand if CSG fails on degenerate meshes

Implementations

impl BooleanClippingProcessor

pub fn new() -> Self

pub fn with_skip_small_cuts(skip_small_cuts: bool) -> Self

Construct with the per-build small-cut skip set (see Self::skip_small_cuts). The router injects the build’s value here; nested boolean operands reuse the same self, and the only cross- processor boolean construction site (CsgSolidProcessor) forwards its own field so a whole CSG tree shares one scoped value.

pub fn take_failures(&self) -> Vec<BoolFailure>

Drain the boolean-failure log accumulated since this processor was created (or the last take_failures call).
