Enum CoordSelectionRule 

#[non_exhaustive]
pub enum CoordSelectionRule {
    Random,
    Cyclic,
    GreedyGradient,
    GreedyGauss,
    StochasticGreedy,
}

Rule for selecting which coordinate to update at each iteration.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Random

Select coordinate uniformly at random.

Cyclic

Cycle through all coordinates in order 0, 1, …, n-1, 0, 1, …

GreedyGradient

Select coordinate with largest absolute gradient component.

GreedyGauss

Gauss-Southwell rule: select i = argmax_i |∂f/∂x_i|.

StochasticGreedy

Randomly sample greedy_subset_size coordinates, pick the one with largest |grad_i|.

Trait Implementations

impl Clone for CoordSelectionRule

fn clone(&self) -> CoordSelectionRule

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CoordSelectionRule

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

Formats the value using the given formatter.

impl Default for CoordSelectionRule

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for CoordSelectionRule

fn eq(&self, other: &CoordSelectionRule) -> 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.
