Struct newdoku::Sudoku

pub struct Sudoku { /* private fields */ }

Contains an 81-size array of Option<u32>.

Implementations

impl Sudoku

pub fn from_str(src: &str) -> Self

Returns a Sudoku from a given src: &str. Digits are parsed as a number in the sudoku while anything else is a blank space. Newlines are ignored.

Examples

use newdoku::Sudoku;

Sudoku::from_str(
    "xxxxxxx9xx9x7xx21xxx4x9xxxxx1xxx8xxx7xx42xxx5xx8xxxx748x1xxxx4xxxxxxxxxxxx9613xxx"
);

pub fn try_insert(&self, loc: (usize, usize), num: u32) -> Result<Self, &str>

Returns a Sudoku that is the same as self but with num inserted at loc: (x, y) (0-indexed) if it can be inserted there by sudoku rules.

pub fn is_full(&self) -> bool

Returns true if self has no empty spaces.

pub fn solution(&self, step: u64, quiet: bool) -> Option<Self>

Returns the solved Sudoku if it exists. If quiet set to false, then prints each iteration while solving.

Examples

use newdoku::Sudoku;

let s = Sudoku::from_str(
    "xxxxxxx9xx9x7xx21xxx4x9xxxxx1xxx8xxx7xx42xxx5xx8xxxx748x1xxxx4xxxxxxxxxxxx9613xxx",
);
assert_eq!(
    s.solution(0, true).unwrap(),
    Sudoku::from_str(
        "157832496396745218284196753415378962763429185928561374831257649672984531549613827"
    )
);
