Struct BezierRetainedLineRegionRoleReport2 

pub struct BezierRetainedLineRegionRoleReport2 { /* private fields */ }

Exact role assignment for retained line-image Bezier boundary loops.

This report is intentionally narrower than arbitrary retained Bezier role assignment. It accepts materialized Bezier/conic fragments only through a certified exact line-image fit, accepts algebraic endpoint-image fragments only when they provide exact endpoint witnesses, lowers those loops to native Contour2 line loops, and then runs exact nesting. This follows Yap’s exact-geometric-computation boundary: unsupported curve families remain explicit evidence gaps rather than being sampled into polygon surrogates. The source counters retain whether role assignment consumed native fit certificates or algebraic endpoint evidence. The containment step uses boundary-first point-in-contour classification as surveyed by Hormann and Agathos, “The Point in Polygon Problem for Arbitrary Polygons,” Computational Geometry 20(3), 131-144 (2001).

Implementations

impl BezierRetainedLineRegionRoleReport2

pub fn new( roles: Vec<BezierRetainedRegionLoopRole>, nesting_depths: Vec<usize>, materialized_fragment_count: usize, algebraic_fragment_count: usize, contours: Vec<Contour2>, ) -> CurveResult<Self>

pub fn with_loop_arrangement_sources( self, loop_arrangement_sources: Vec<Option<Vec<BezierRetainedFragmentSource2>>>, ) -> CurveResult<Self>

Attaches one optional arrangement source trail per retained loop.

pub fn roles(&self) -> &[BezierRetainedRegionLoopRole]

Returns one assigned role per retained boundary loop.

pub fn nesting_depths(&self) -> &[usize]

Returns the certified count of containing loops for each retained loop.

pub const fn materialized_fragment_count(&self) -> usize

Returns how many materialized fragments contributed certified line-image fits.

pub const fn algebraic_fragment_count(&self) -> usize

Returns how many algebraic endpoint-image fragments contributed exact endpoints.

pub const fn has_algebraic_fragments(&self) -> bool

Returns true when algebraic endpoint evidence contributed to the line contours.

pub fn contours(&self) -> &[Contour2]

Returns exact native line contours used for role assignment.

pub fn loop_arrangement_sources( &self, ) -> Option<&[Option<Vec<BezierRetainedFragmentSource2>>]>

Returns per-loop arrangement/source provenance when the report has it.

pub fn material_loop_indices(&self) -> Vec<usize>

Returns loop indices assigned as material.

pub fn hole_loop_indices(&self) -> Vec<usize>

Returns loop indices assigned as holes.
