Enum Spacing 

pub enum Spacing {
    Centripetal,
    Chordal,
    Uniform,
}

How to spread parameters over the points.

Variants

Centripetal

Parameter spacing goes as the square root of the chord.

The default, and what a fitted curve is expected to look like: it neither loops the way uniform spacing does on unevenly spread points nor overshoots the way chord length does at a sharp turn.

Chordal

Parameter spacing proportional to the chord.

Uniform

Equal parameter spacing, ignoring the points entirely.

Correct only when the points really are evenly spread; otherwise it is the one that loops.

Trait Implementations

impl Clone for Spacing

fn clone(&self) -> Spacing

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Spacing

impl Debug for Spacing

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

Formats the value using the given formatter.

impl Default for Spacing

fn default() -> Spacing

Returns the “default value” for a type.

impl Eq for Spacing

impl PartialEq for Spacing

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