Struct TileId 

pub struct TileId {
    pub x: i32,
    pub y: i32,
}

A tile address on the integer grid. Coordinates may be negative.

Fields

x: i32

y: i32

Implementations

impl TileId

pub fn new(x: i32, y: i32) -> Self

pub fn origin(self, extent: u32) -> Option<Coord<i32>>

This tile’s origin in global coordinates — self · extent, the global position its local [0, 0] corner maps to. Add it to a tile-local coordinate to lift it into the global frame, or subtract it to drop a global coordinate into this tile’s local frame.

Returns None if self · extent overflows i32 (a tile far outside the representable range for this extent).

let origin = TileId::new(2, 3).origin(25).expect("in range");
assert_eq!(origin, Coord { x: 50, y: 75 });
assert_eq!(Coord { x: 4, y: 1 } + origin, Coord { x: 54, y: 76 }); // local → global
assert_eq!(Coord { x: 54, y: 76 } - origin, Coord { x: 4, y: 1 }); // global → local
