Enum ExactCurveRefusal

pub enum ExactCurveRefusal {

    UnsupportedSurface,
    NonFinite,
    Degenerate,
    PartialOverlap,
}

Why an exact curve intersection was not computed.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

UnsupportedCurve

The curve is not a line, circle or ellipse. B-spline curves go through the certified numeric path instead.

UnsupportedSurface

The surface is a B-spline surface or an unknown kind.

NonFinite

An input coordinate, radius or angle is NaN or infinite.

Degenerate

A frame is singular, a direction is zero, or a radius is not positive: there is no curve or surface to intersect.

PartialOverlap

The curve lies in the cone’s quadric but crosses its apex, so only part of it is on the modelled nappe: the overlap is a ray, which is neither a finite point set nor the whole curve.

Trait Implementations

impl Clone for ExactCurveRefusal

fn clone(&self) -> ExactCurveRefusal

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ExactCurveRefusal

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

Formats the value using the given formatter.

impl PartialEq for ExactCurveRefusal

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