Methods
impl Square
[src]
fn new(sq: u8) -> Square
Create a new square, given an index. Note: It is invalid, but allowed, to pass in a number >= 64. Doing so will crash stuff.
fn make_square(rank: u8, file: u8) -> Square
Make a square given a rank and a file Note: It is invalid, but allowed, to pass in a rank or file >= 8. Doing so will crash stuff.
fn up(&self) -> Option<Square>
If there is a square above me, return that. Otherwise, None.
fn forward(&self, color: Color) -> Option<Square>
If there is a square "forward", given my Color
, go in that direction. Otherwise, None.
fn backward(&self, color: Color) -> Option<Square>
If there is a square "backward" given my Color
, go in that direction. Otherwise, None.
fn down(&self) -> Option<Square>
If there is a square below me, return that. Otherwise, None.
fn left(&self) -> Option<Square>
If there is a square to the left of me, return that. Otherwise, None.
fn right(&self) -> Option<Square>
If there is a square to the right of me, return that. Otherwise, None.
fn uup(&self) -> Square
If there is a square above me, return that. Otherwise, return invalid data to crash the program.
fn udown(&self) -> Square
If there is a square below me, return that. Otherwise, return invalid data to crash the program.
fn uleft(&self) -> Square
If there is a square to the left of me, return that. Otherwise, return invalid data to crash the program.
fn uright(&self) -> Square
If there is a square to the right of me, return that. Otherwise, return invalid data to crash the program.
fn uforward(&self, color: Color) -> Square
If there is a square "forward", given my color, return that. Otherwise, return invalid data to crash the program.
fn ubackward(&self, color: Color) -> Square
If there is a square "backward", given my color, return that. Otherwise, return invalid data to crash the program.
fn rank(&self) -> u8
Return the rank given this square.
fn file(&self) -> u8
Return the file given this square.
fn to_int(&self) -> u8
Convert this square to an integer.
fn to_index(&self) -> usize
Convert this Square
to a usize
for table lookup purposes
fn from_string(s: String) -> Option<Square>
Convert a UCI String
to a square. If invalid, return None
