Struct PointingSegment 

pub struct PointingSegment<'a, P: PointMut> { /* private fields */ }

A segment borrowing two mutable endpoints instead of storing copies.

Mirrors model::pointing_segment from geometries/pointing_segment.hpp:39-72. Boost stores nullable raw pointers because its segment iterator requires default construction. Rust represents only the valid, non-null state and uses the borrow checker to prevent the endpoints from outliving their source.

Implementations

impl<'a, P: PointMut> PointingSegment<'a, P>

pub const fn new(start: &'a mut P, end: &'a mut P) -> Self

Borrow two endpoints as a segment.

Mirrors pointing_segment(p1, p2) from geometries/pointing_segment.hpp:67-71 while eliminating the C++ model’s nullable default state.

pub const fn start(&self) -> &P

Borrow the first endpoint.

pub const fn end(&self) -> &P

Borrow the second endpoint.

Trait Implementations

impl<'a, P: Debug + PointMut> Debug for PointingSegment<'a, P>

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

Formats the value using the given formatter.

impl<P: PointMut> Geometry for PointingSegment<'_, P>

type Kind = SegmentTag

One of the *Tag types from geometry_tag.

type Point = P

The point type this geometry is built from. For a value modelling Point, this is Self.

impl<P: PointMut> IndexedAccess for PointingSegment<'_, P>

fn get_indexed<const I: usize, const D: usize>(&self) -> P::Scalar

Read coordinate D of corner I.

fn set_indexed<const I: usize, const D: usize>(&mut self, value: P::Scalar)

Write coordinate D of corner I.
