    Left,
    Right,
}

There are four cardinal directions: Up, down, left, and right. You can also think of these as north, south, west and east.

Variants

Up

Down

Left

Right

Implementations

impl Direction

pub fn turn_left(&self) -> Direction

Turn one step to the left.

pub fn turn_right(&self) -> Direction

Turn one step to the right.

pub fn reverse(&self) -> Direction

Reverse direction.

pub fn turn(&self, steps: isize) -> Direction

Turn an arbitrary number of steps. Positive numbers turn to the left, negative numbers turn to the right.
