Struct LambdaCvConfig 

#[non_exhaustive]
pub struct LambdaCvConfig {
    pub lambdas: Vec<f64>,
    pub n_folds: usize,
    pub max_iter: usize,
    pub tol: f64,
    pub seed: u64,
}

Configuration for lambda cross-validation.

Construct via LambdaCvConfig::default(), then assign the fields you need (e.g. let mut c = LambdaCvConfig::default(); c.field = …;). This struct is #[non_exhaustive], so external crates cannot build it with a struct literal — not even functional-update ..Default::default() form.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

lambdas: Vec<f64>

Candidate lambda values to evaluate.

n_folds: usize

Number of folds (0 = leave-one-out).

max_iter: usize

Maximum Karcher iterations per fold.

tol: f64

Karcher convergence tolerance.

seed: u64

RNG seed for fold assignment.
