Enum sudoku_variants::solver::Solution [−][src]
An enumeration of the different ways a Sudoku can be solveable. Note that
this may be relative to the solver, since an imperfect solver may be unable
to continue at some point, yielding Solution::Ambiguous
, where the Sudoku
is actually uniquely solveable or impossible.
Variants
Indicates that the Sudoku is not solveable at all.
Unique(SudokuGrid)
Indicates that the Sudoku has a unique solution, which is wrapped in this instance.
Indicates that the Sudoku has multiple solutions or, at least, that the solver was unable to find a unique one or prove it is impossible.
Implementations
impl Solution
[src]
pub fn union(self, other: Solution) -> Solution
[src]
Computes the union of two solutions. This is defined as follows:
- If one solution is
Solution::Impossible
, the other one is returned. - If one solution is
Solution::Ambiguous
then the result is also ambiguous - If both solutions are
Solution::Unique
with solution gridsg1
andg2
, then the result isSolution::Unique(g1)
ifg1 == g2
andSolution::Ambiguous
otherwise.
