A Rust Library for iterating over 2D structures in spiral patterns.
Add this to your Cargo.toml:
toml
[dependencies]
spiral = "0.1"
And this to your crate root:
rust
extern crate spiral;
rust
let center_x = 3;
let center_y = 3;
let radius = 4;
for (x, y) in ManhattanIterator::new(center_x, center_y, radius) {
// Iterates over 7x7 2D array with 'x' & 'y' following this pattern:
//
// 0 0 0 23 0 0 0
// 0 0 22 12 24 0 0
// 0 21 11 5 13 25 0
// 20 10 4 1 2 6 14
// 0 19 9 3 7 15 0
// 0 0 18 8 16 0 0
// 0 0 0 17 0 0 0
