Struct SearchData 

pub struct SearchData<'a> {
    pub x: &'a [Vec<f64>],
    pub y: &'a [f64],
    pub sample_weight: Option<&'a [f64]>,
    pub samples_info_sets: &'a [(NaiveDateTime, NaiveDateTime)],
}

The data a search cross-validates on; all slices are aligned by sample.

Fields

x: &'a [Vec<f64>]

Features, one row per sample.

y: &'a [f64]

Binary labels (0.0 or 1.0).

sample_weight: Option<&'a [f64]>

Optional non-negative sample weights, used both to fit and to score.

samples_info_sets: &'a [(NaiveDateTime, NaiveDateTime)]

Each label’s (start, end) span, used to purge and embargo the folds.
