Enum Continuity 

pub enum Continuity {
    C0,
    G1,
    C1,
    G2,
    C2,
    CInfinity,
}

How smooth a curve or surface is.

Ordered from least to most smooth, so >= is a meaningful test.

Variants

C0

Positions agree; tangents may not. A corner.

G1

Tangent directions agree, but their magnitudes need not. Enough for a visually smooth join, and the usual requirement for a wire.

C1

First derivatives agree exactly.

G2

Curvature agrees.

C2

Second derivatives agree exactly.

CInfinity

Differentiable to any order: an analytic surface away from its degeneracies.

Trait Implementations

impl Clone for Continuity

fn clone(&self) -> Continuity

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Continuity

impl Debug for Continuity

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

Formats the value using the given formatter.

impl Eq for Continuity

impl Ord for Continuity

fn cmp(&self, other: &Continuity) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Continuity

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

impl PartialOrd for Continuity

fn partial_cmp(&self, other: &Continuity) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
