Struct BezierRetainedLineOverlapSplit2 

pub struct BezierRetainedLineOverlapSplit2 { /* private fields */ }

Exact split evidence for a positive-dimensional line-image overlap.

The stored ranges are the affine parameters of the certified line-segment images, not arbitrary sampled Bezier parameters. This is the next overlap ownership artifact after pair reporting: future graph splitting can consume the overlap segment endpoints and exact affine ranges while still refusing to conflate them with curve parameters for non-affine line-image Beziers. That distinction is the Yap exact-object boundary in practice; see Yap (1997). The positive-dimensional segment itself is the ordinary collinear overlap from exact line-line intersection, a standard clipping degeneracy discussed by Foster, Hormann, and Popa (2019).

Implementations

impl BezierRetainedLineOverlapSplit2

pub fn new( first_fragment_index: usize, second_fragment_index: usize, overlap_segment: LineSeg2, first_line_range: ParamRange, second_line_range: ParamRange, extent: BezierRetainedLineOverlapExtent2, ) -> CurveResult<Self>

Constructs exact line-image split evidence.

pub const fn first_fragment_index(&self) -> usize

Returns the lower graph-fragment index.

pub const fn second_fragment_index(&self) -> usize

Returns the higher graph-fragment index.

pub const fn overlap_segment(&self) -> &LineSeg2

Returns the exact overlap segment.

pub const fn first_line_range(&self) -> &ParamRange

Returns the affine line range on the first fragment image.

pub const fn second_line_range(&self) -> &ParamRange

Returns the affine line range on the second fragment image.

pub const fn extent(&self) -> BezierRetainedLineOverlapExtent2

Returns whether the overlap is full or partial on each side.

Trait Implementations

impl Clone for BezierRetainedLineOverlapSplit2

fn clone(&self) -> BezierRetainedLineOverlapSplit2

impl PartialEq for BezierRetainedLineOverlapSplit2

fn eq(&self, other: &BezierRetainedLineOverlapSplit2) -> bool
