Crate spiral

Iterators to iterate 2D structures in spiral patterns

Usage

This crate is on crates.io and can be used by adding spiral to the dependencies in your project’s Cargo.toml.

[dependencies]
spiral = "0.2"

Examples

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`.
}

Structs

ChebyshevIterator

An iterator iterating in a spiral fashion with the Chebyshev distance function.

ManhattanIterator

An iterator iterating in a spiral fashion with the Manhattan distance function.

Traits

Int

Simple trait so we don’t have to wrap write all the num signatures that we want every time.
