Implementations§

source§

impl Point

source

pub const fn new(x: i64, y: i64) -> Self

Creates a new Point from (x,y) coordinates.

source

pub const fn from_dir_coords(dir: Dir, a: i64, b: i64) -> Self

§Example
let origin = Point::zero();
assert_eq!(origin, Point::new(0, 0));
source

pub const fn coord(&self, dir: Dir) -> i64
