Struct AllDifferent

pub struct AllDifferent { /* private fields */ }

Implementations

impl AllDifferent

pub 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<dyn 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<dyn Constraint>>

Substitute the “from” variable with the “to” variable.
