Struct CurveParams

Source

pub struct CurveParams {
    pub roll_type: RollType,
    pub step_b: usize,
    pub step_c: usize,
    pub curve_scale: f64,
}

Expand description

The parameters that define a curvature calculation.

Grouped into one struct because they travel together through every layer, and a function taking five bare numbers is easy to call wrongly.

Fields§

§roll_type: RollType§step_b: usize

Half the rolling-mean window, minus one: the window is 2 * step_b + 1.

§step_c: usize

Distance from the midpoint base to each side of the curve window.

§curve_scale: f64

Implementations§

Source §

impl CurveParams

Source

pub fn lead_in(&self) -> usize

How many bases at each end of a piece receive no score.

The rolling mean consumes step_b on each side and the distance window a further step_c, plus one for the triplet. A piece of length n therefore yields n - 2 * lead_in() scores, the first of which belongs to the base at offset lead_in(). This matches the reference implementation, which indexes curvature from curvstep + stepone.
