Struct LineCurve 

pub struct LineCurve { /* private fields */ }

A straight line, parameterized by length from its origin.

Implementations

impl LineCurve

pub const fn new(axis: Axis) -> Self

A line along axis, spanning LINE_EXTENT either side of its origin.

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

A line segment between two distinct points.

The domain runs from zero to the distance between them, so the parameter is arc length, which makes every length query along the segment exact.

Errors

OgeomError::Construction if the points coincide.

pub fn over(axis: Axis, 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) -> Axis

The underlying axis.

Trait Implementations

impl Clone for LineCurve

fn clone(&self) -> LineCurve

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for LineCurve

impl Curve3d for LineCurve

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

The parameter interval over which the curve is defined.

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

The point at u.

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

The first derivative at u.

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

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

fn kind(&self) -> CurveKind

What kind of curve this is.

fn continuity(&self) -> Continuity

How smooth the curve is across its domain.

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 tangent_at(&self, u: f64, tol: Tolerances) -> OgeomResult<Direction>

The unit tangent at u.

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

The curvature at u.

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

The start point.

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

The end point.

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

Bring u into the domain, wrapping if the curve is periodic.

impl Debug for LineCurve

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

Formats the value using the given formatter.

impl From<LineCurve> for Curve

fn from(c: LineCurve) -> Self

Converts to this type from the input type.

impl PartialEq for LineCurve

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