Struct Line2d 

pub struct Line2d { /* private fields */ }

A straight line in the plane, parameterized by length.

Implementations

impl Line2d

pub fn segment(from: Point2, to: Point2, tol: Tolerances) -> OgeomResult<Self>

A segment between two distinct points, parameterized by arc length.

Errors

OgeomError::Construction if the points coincide.

pub fn over(axis: Axis2, start: f64, end: f64) -> OgeomResult<Self>

A line over an explicit parameter range.

Errors

OgeomError::Construction if the range is empty or non-finite.

pub const fn axis(&self) -> Axis2

The underlying axis.

Trait Implementations

impl Clone for Line2d

fn clone(&self) -> Line2d

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Line2d

impl Curve2d for Line2d

fn domain(&self) -> (f64, f64)

The parameter interval over which the curve is defined.

fn point_at(&self, u: f64, tol: Tolerances) -> OgeomResult<Point2>

The point at u.

fn d1_at(&self, u: f64, tol: Tolerances) -> OgeomResult<Vector2>

The first derivative at u.

fn derivatives_at( &self, u: f64, n: usize, tol: Tolerances, ) -> OgeomResult<Vec<Vector2>>

Derivatives up to order n, with result[0] the point itself.

fn kind(&self) -> CurveKind

What kind of curve this is.

fn is_closed(&self, _tol: Tolerances) -> bool

Whether the curve’s ends meet.

fn is_periodic(&self) -> bool

Whether the curve continues past its domain by repeating.

fn start(&self, tol: Tolerances) -> OgeomResult<Point2>

The start point.

fn end(&self, tol: Tolerances) -> OgeomResult<Point2>

The end point.

impl Debug for Line2d

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

Formats the value using the given formatter.

impl From<Line2d> for PlanarCurve

fn from(c: Line2d) -> Self

Converts to this type from the input type.

impl PartialEq for Line2d

fn eq(&self, other: &Line2d) -> 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.
