Enum CoordSelection 

pub enum CoordSelection {
    Cyclic,
    Random,
}

Coordinate-selection order for the coordinate-descent solver.

Mirrors sklearn’s Lasso(selection=...) / ElasticNet(selection=...) parameter (_coordinate_descent.py, __init__ default 'cyclic').

Variants

Cyclic

Sweep coordinates 0..n_features in order each pass (sklearn default, selection='cyclic'). Bit-exact to sklearn’s cyclic path.

Random

Visit coordinates in a random order each pass (sklearn selection='random'). Often converges faster when features are correlated; the Lasso optimum is unique here so it reaches the same limit (sklearn _cd_fast.pyx enet_coordinate_descent random branch).

Trait Implementations

impl Clone for CoordSelection

fn clone(&self) -> CoordSelection

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for CoordSelection

impl Debug for CoordSelection

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for CoordSelection

fn default() -> CoordSelection

Returns the “default value” for a type.

impl Eq for CoordSelection

impl PartialEq for CoordSelection

fn eq(&self, other: &CoordSelection) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
