Struct PsiSlice 

pub struct PsiSlice {
    pub range: Range<usize>,
    pub latent_dim: Option<usize>,
}

Reference for the column / coordinate range a penalty operates over.

Mirrors BlockwisePenalty::col_range for the β tier and is the natural per-observation flat index for the extension-coordinate tier (matching the LatentCoordValues row-major flat layout: n * d + a).

Fields

range: Range<usize>

Inclusive-start, exclusive-end flat range into the underlying ext-coordinate vector.

latent_dim: Option<usize>

For latent-coordinate slices: the latent dimensionality, used to reshape the flat slice into per-row (n_obs, d) blocks.

Implementations

impl PsiSlice

pub fn full(len: usize, latent_dim: Option<usize>) -> Self

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool
