    pub y: isize,
}

y: isize

Implementations

impl ICoord

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

Create a new ICoord

pub fn quadrant(self) -> usize

Return the quadrant this coordinate is in.

• 1: +X, +Y
• 2: -X, +Y
• 3: -X, -Y
• 4: +X, -Y

Zeroes are treated as positive.

assert_eq!(ICoord::new(4, 5).quadrant(), 1);
assert_eq!(ICoord::new(-3, -2).quadrant(), 3);
// Zero is treated as positive
assert_eq!(ICoord::new(0, -8).quadrant(), 4);
assert_eq!(ICoord::new(0, 0).quadrant(), 1);

pub fn to_coord(self) -> Option<Coord>

Try to convert this to a Coord. Returns None in case any part is negative.

pub fn neighbors4(self) -> [ICoord; 4]

Get a list of this coordinate’s orthagonal neighbors. They are given in clockwise order starting with the neighbor to the north, as if each of Direction4::DIRECTIONS had been added to them.

assert_eq!(
    ICoord::new(5, 7).neighbors4(),
    [
        ICoord::new(5, 6),
        ICoord::new(6, 7),
        ICoord::new(5, 8),
        ICoord::new(4, 7),
    ]
);

let origin = ICoord::new(-7, -12);
assert_eq!(
    origin.neighbors4()[..],
    Direction4::DIRECTIONS.iter().map(|dir| origin + *dir).collect::<Vec<_>>()[..],
);

pub fn neighbors8(self) -> [ICoord; 8]

Get a list of this coordinate’s orthagonal and diagonal neighbors. They are given in clockwise order starting with the neighbor to the north, as if each of Direction8::DIRECTIONS had been added to them.

assert_eq!(
    ICoord::new(5, 7).neighbors8(),
    [
        ICoord::new(5, 6),
        ICoord::new(6, 6),
        ICoord::new(6, 7),
        ICoord::new(6, 8),
        ICoord::new(5, 8),
        ICoord::new(4, 8),
        ICoord::new(4, 7),
        ICoord::new(4, 6),
    ]
);

let origin = ICoord::new(-7, -12);
assert_eq!(
    origin.neighbors8()[..],
    Direction8::DIRECTIONS.iter().map(|dir| origin + *dir).collect::<Vec<_>>()[..],
);
