Struct Curve 

pub struct Curve {
    pub id: String,
    pub kind: CurveKind,
    pub points: Vec<CurvePoint>,
}

A piecewise-linear mapping from x to y (§2.3). Static.

points has x strictly increasing and length ≥ 2.

Fields

id: String

String identifier for this curve.

kind: CurveKind

Semantic kind, used to select validation rules.

points: Vec<CurvePoint>

Ordered sample points with strictly increasing x-values. Length ≥ 2.

Implementations

impl Curve

pub fn eval(&self, x: f64) -> f64

Evaluates the curve at x using piecewise-linear interpolation.

Implements §2.3: when x is inside the range the bracketing segment is used directly. When x is outside the range the nearest endpoint segment is extended linearly (extrapolation).

For single-point curves, returns the y-value of that point (constant).

Trait Implementations

impl Clone for Curve

fn clone(&self) -> Curve

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Curve

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

Formats the value using the given formatter.
