spiral

文档

迭代器用于在螺旋模式中遍历二维结构

用法

此包位于 crates.io 上，可以通过在项目的 Cargo.toml 依赖中添加 spiral 来使用。

[dependencies]
spiral = "0.2"

示例

use spiral::ChebyshevIterator;

let center_x = 3;
let center_y = 3;
let radius = 4;
let iterator = ChebyshevIterator::new(center_x, center_y, radius);
for (x, y) in iterator {
    // Iterates over a 7x7 2D array with `x` & `y`.
}

use spiral::ManhattanIterator;

let center_x = 3;
let center_y = 3;
let radius = 4;
for (x, y) in ManhattanIterator::new(center_x, center_y, radius) {
    // Iterates over a 7x7 2D array with `x` & `y`.
}
