Struct RegularizationPath 

pub struct RegularizationPath { /* private fields */ }

A full regularization path — one RegLine per coefficient.

Implements IntoIterator, so chart.draw_series(path) draws every line at once. For a per-feature legend, iterate RegularizationPath::lines and call draw_series once per line with its name()/color().

Implementations

impl RegularizationPath

pub fn new( strengths: &[f64], coefficients: &[Vec<f64>], ) -> Result<Self, StatsError>

Build from strengths (x positions) and a coefficients matrix indexed [strength_row][feature_col] — i.e. coefficients[i][j] is feature j’s value at strength strengths[i].

Zero-crossing markers are on by default. Errors on empty input or a ragged matrix (rows of differing width, or a row count that does not match strengths).

pub fn feature_names<S: Into<String>, I: IntoIterator<Item = S>>( self, names: I, ) -> Self

Attach feature names (used as per-line legend labels). Extra names are ignored; missing ones leave that line unnamed.

pub fn zero_markers(self, show: bool) -> Self

Enable/disable zero-crossing markers on every line.

pub fn stroke_width(self, width: u32) -> Self

Set a common stroke width for every line.

pub fn lines(&self) -> Vec<RegLine>

The per-coefficient lines, cloned — iterate these to draw each with its own legend entry.
