Enum VariableSelectionHeuristic 

pub enum VariableSelectionHeuristic {
    FirstUnassigned,
    MinDomain,
    MaxDomain,
    MaxDegree,
    MinDomainMaxDegree,
}

Variable selection heuristics for search.

Variants

FirstUnassigned

Select first unassigned variable

MinDomain

Select variable with smallest domain (most constrained)

MaxDomain

Select variable with largest domain

MaxDegree

Select variable involved in most constraints

MinDomainMaxDegree

Combination: min-domain, then max-degree

Trait Implementations

impl Clone for VariableSelectionHeuristic

fn clone(&self) -> VariableSelectionHeuristic

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for VariableSelectionHeuristic

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

Formats the value using the given formatter.

impl PartialEq for VariableSelectionHeuristic

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