Struct Trimmed2d 

pub struct Trimmed2d { /* private fields */ }

Another planar curve restricted to a sub-interval.

Implementations

impl Trimmed2d

pub fn new( basis: PlanarCurve, start: f64, end: f64, tol: Tolerances, ) -> OgeomResult<Self>

Restrict basis to [start, end].

Errors

OgeomError::Domain if the range is empty or leaves the basis curve’s domain.

pub const fn basis(&self) -> &PlanarCurve

The curve being trimmed.

pub const fn is_reversed(&self) -> bool

Whether the curve runs backwards along its underlying curve.

Part of the curve’s state and not derivable from its basis curve, so anything that has to reproduce this curve exactly (the native format above all) needs to be able to read it.

Trait Implementations

impl Clone for Trimmed2d

fn clone(&self) -> Trimmed2d

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Curve2d for Trimmed2d

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 Trimmed2d

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

Formats the value using the given formatter.

impl From<Trimmed2d> for PlanarCurve

fn from(c: Trimmed2d) -> Self

Converts to this type from the input type.

impl PartialEq for Trimmed2d

fn eq(&self, other: &Trimmed2d) -> 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.
