Struct CvResults 

pub struct CvResults {
    pub scorer_names: Vec<String>,
    pub test_scores: Vec<Vec<f64>>,
    pub train_scores: Option<Vec<Vec<f64>>>,
    pub fit_times: Vec<Duration>,
    pub score_times: Vec<Duration>,
}

Results of a cross_validate run.

Scores are stored as [scorer][fold]. Use mean_test_score / std_test_score (by index or by name) for summaries.

Fields

scorer_names: Vec<String>

Metric names, in the order they were supplied.

test_scores: Vec<Vec<f64>>

Test scores as [scorer][fold].

train_scores: Option<Vec<Vec<f64>>>

Train scores as [scorer][fold], if return_train_scores was set.

fit_times: Vec<Duration>

Wall-clock fit time per fold.

score_times: Vec<Duration>

Wall-clock score time per fold.
