Implementations

impl SegmentInterval

pub(crate) fn from_projection( segment: Segment, projection: ParamPair, edge_id: u32 ) -> Self

Creates a new interval from projection parameters.

Arguments

• segment - an original segment. Projection parameters correspond to this segment.

• projection - parameters of endpoints a and b of the interval to be created.

• edge_id - ID of the original edge / segment.

Panics

May panic if projection parameters are not between 0 and 1 (inclusive) or if first projection parameter is larger or equal to the second projection parameter.

pub(crate) fn new( segment: Segment, is_a_corner: bool, is_b_corner: bool, edge_id: u32 ) -> Self

Creates a new segment interval.

Panics

May panic if segment has zero length.

pub(crate) fn a_corner(&self) -> Option<Point<f32>>

Returns the corner point of the original edge (see Self::edge_id()) if it corresponds to the endpoint of self.

pub(crate) fn b_corner(&self) -> Option<Point<f32>>

Returns the corner point of the original edge (see Self::edge_id()) if it corresponds to the endpoint of self.

pub(crate) fn edge_id(&self) -> u32

Returns edge ID of the original edge.

pub(crate) fn distance_to_point(&self, point: Point<f32>) -> f32

pub(crate) fn project_point(&self, point: Point<f32>) -> Point<f32>

pub(crate) fn cross(&self, a: Point<f32>, b: Point<f32>) -> SegmentCross

Calculates the cross point of an optimal path from a point a to a point b via the interval.

pub(crate) fn project_onto_segment( &self, eye: Point<f32>, target: Segment ) -> SegmentOnSegmentProjection

Returns projection of self onto a target segment from a given perspective.

Arguments

• eye - projection perspective.

• target - self is projected onto this target.

Trait Implementations

impl Clone for SegmentInterval

fn clone(&self) -> SegmentInterval

Returns a copy of the value.

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

Performs copy-assignment from source.
