Struct HashState 

pub struct HashState { /* private fields */ }

Trait Implementations

impl Clone for HashState

fn clone(&self) -> HashState

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for HashState

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for HashState

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for HashState

fn eq(&self, other: &HashState) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl State for HashState

fn to_array(&self) -> [u8; 9]

Returns the board as an array of length 9.

fn from_array(arr: &[u8; 9]) -> HashState

Returns the State from the board. If the array is illegal, i.e. not a permutation of 0..9, the result is undefined.

fn hash(&self) -> u32

Returns the hash of the states. It should be in range of 0..NUMBER_OF_STATES.

fn neighbors(&self) -> Vec<(Direction, Self)>

fn move_blank<I: Iterator<Item = usize>>( &self, indices: I, offset: isize, ) -> Option<Self>

fn up(&self) -> Option<Self>

fn down(&self) -> Option<Self>

fn left(&self) -> Option<Self>

fn right(&self) -> Option<Self>
