Enum Group

pub enum Group {
    Box(Vec<Option<Element>>),
    Stack(Vec<Option<Element>>),
    Band(Vec<Option<Element>>),
}

A subdivision of the main sudoku; the smallest grouping to which rules are applied.

Variants

Box(Vec<Option<Element>>)

A square set of elements.

A subdivision of a sudoku.

Rule

Each box may contain each element value only once.

Stack(Vec<Option<Element>>)

A vertical set of elements.

A subdivision of a sudoku.

Rule

Each stack may contain each element value only once.

Band(Vec<Option<Element>>)

A horizontal set of elements.

A subdivision of a sudoku.

Rule

Each band may contain each element value only once.

Dimensionality

In n dimensions, n - 1 bands apply to each element. Each is linearly independent from the others and from the relevant stack.

Implementations

impl Group

pub fn is_valid(&self) -> bool

Whether a group is valid (contains no errors).

A group is considered valid if it contains only unique elements (ignoring empty elements).

pub fn is_complete(&self) -> bool

Whether a group is complete.

A group is considered complete if it contains every possible element value exactly once.

pub fn elements(&self) -> Vec<Option<Element>>

Returns an owned copy of the group’s constituent elements.

impl Default for Group

fn default() -> Self
