pub struct AllDifferent { /* fields omitted */ }

Methods

impl AllDifferent

fn new<'a, I>(vars: I) -> Self where
    I: IntoIterator<Item = &'a VarToken>, 

Allocate a new All Different constraint.

Examples

let mut send_more_money = puzzle_solver::Puzzle::new();
let vars = send_more_money.new_vars_with_candidates_1d(8,
        &[0,1,2,3,4,5,6,7,8,9]);

puzzle_solver::constraint::AllDifferent::new(&vars);

Trait Implementations

impl Constraint for AllDifferent

fn vars<'a>(&'a self) -> Box<Iterator<Item = &'a VarToken> + 'a>

An iterator over the variables that are involved in the constraint.

fn on_assigned(
    &self,
    search: &mut PuzzleSearch,
    var: VarToken,
    val: Val
) -> PsResult<()>

Applied after a variable has been assigned.

fn on_updated(&self, search: &mut PuzzleSearch) -> PsResult<()>

Applied after a variable's candidates has been modified.

fn substitute(&self, from: VarToken, to: VarToken) -> PsResult<Rc<Constraint>>

Substitute the "from" variable with the "to" variable.
