Implementations

impl Direction9

pub const DIRECTIONS: &'static [Direction9] = _

pub fn rotate(self, rot: Rotation) -> Self

Rotate this by the given amount.

pub fn rotate_by(self, steps_clockwise: i32) -> Self

Get this direction, rotated by this many steps clockwise. Negative numbers go counter-clockwise.

pub fn flip(self) -> Self

Flip this direction.

pub fn deltas(self) -> CoordVec

Get the deltas a step in this direction would result in, as an CoordVec.
