Struct Position

pub struct Position { /* private fields */ }

グリッド上の位置を表す。

Implementations

impl Position

pub fn new(x: usize, y: usize, h: usize, w: usize) -> Self

(0, 0) ~ (h - 1, w - 1)の長方形内の位置(x, y)を表すPositionを返す。

pub fn x(self) -> usize

x方向の位置

pub fn y(self) -> usize

y方向の位置

pub fn mov(self, d: Dir) -> Option<Self>

(self.x + d.dx, self.y + d.dy)に相当するPositionをSomeに包んで返す。

移動先が(0, 0)から(h - 1, w - 1)の外部にある場合、Noneを返す。

Trait Implementations

impl Clone for Position

fn clone(&self) -> Position

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Position

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

Formats the value using the given formatter.

impl Default for Position

fn default() -> Position

Returns the “default value” for a type.

impl PartialEq for Position

fn eq(&self, other: &Position) -> 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.
