Struct ContourSplitMap 

pub struct ContourSplitMap { /* private fields */ }

Per-segment split parameters for a contour.

Every segment starts with 0 and 1 so downstream fragment assembly can build intervals directly after event parameters are merged in.

Implementations

impl ContourSplitMap

pub fn new(segment_splits: Vec<Vec<Real>>) -> CurveResult<Self>

Constructs a split map from already-normalized per-segment parameters.

pub fn with_segment_count(segment_count: usize) -> Self

Constructs a split map containing only segment endpoints.

pub fn from_intersections( segment_count: usize, intersections: &ContourIntersectionSet, operand: ContourOperand, policy: &CurvePolicy, ) -> Classification<Self>

Builds a split map from one contour-pair event set.

pub fn segments(&self) -> &[Vec<Real>]

Returns the split parameters for all segments.

pub fn params_for_segment(&self, segment_index: usize) -> Option<&[Real]>

Returns the split parameters for one segment.

pub fn segment_count(&self) -> usize

Returns the segment count represented by this map.

pub fn is_empty(&self) -> bool

Returns true when the map contains no segments.

pub fn merge_intersections( &mut self, intersections: &ContourIntersectionSet, operand: ContourOperand, policy: &CurvePolicy, ) -> Classification<()>

Merges another contour-pair event set into this split map.

pub fn split_points(&self) -> Vec<SegmentSplitPoint>

Returns all split points flattened in segment order.

Trait Implementations

impl Clone for ContourSplitMap

fn clone(&self) -> ContourSplitMap

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ContourSplitMap

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

Formats the value using the given formatter.

impl PartialEq for ContourSplitMap

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