Struct SurfaceJet 

pub struct SurfaceJet {
    pub point: Point,
    pub du: Vector,
    pub dv: Vector,
    pub d2u: Vector,
    pub duv: Vector,
    pub d2v: Vector,
}

A surface’s point and its derivatives through second order, at one place.

What a foot-point solve needs in one go; see Surface::jet_at.

Fields

point: Point

The point at the parameters asked for.

du: Vector

The first derivative along u.

dv: Vector

The first derivative along v.

d2u: Vector

The second derivative along u.

duv: Vector

The mixed second derivative.

d2v: Vector

The second derivative along v.

Trait Implementations

impl Clone for SurfaceJet

fn clone(&self) -> SurfaceJet

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for SurfaceJet

impl Debug for SurfaceJet

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

Formats the value using the given formatter.

impl PartialEq for SurfaceJet

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