Struct msolve::Sudoku

pub struct Sudoku { /* fields omitted */ }

Structure that represents a sudoku

Implementations

impl Sudoku

pub fn to_array(&self) -> [u8; 81]

Convert the sudoku into a [u8; 81] containing the numerical form of each solved square

pub fn to_bytes(&self) -> [u8; 81]

pub fn iter(self) -> SolutionIterator

Returns an iterator over all solutions

pub fn solve_one(self) -> Option<Self>

Get the first solution.

pub fn solve_unique(self) -> Option<Self>

Returns the first solution if it is uniquely solvable, otherwise returns None

pub fn count_solutions(self, n: usize) -> usize

Counts the number of solutions, up to maximum of n

pub fn has_single_solution(self) -> bool

Check whether the sudoku has exactly one solution without returning the solution

pub fn has_solution(self) -> bool

pub const fn empty() -> Self

Returns an empty sudoku grid, alternative to Sudoku::from([0; 81]) or Sudoku::from(vec![])

pub fn solve_difficulty(self) -> usize

Returns the number of steps to find the first solution, approximately proportional to difficulty

pub fn solve_unique_difficulty(self) -> usize

Returns the number of steps to find the first two solutions, approximately proportional to difficulty
