Crate spiral [−] [src]
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 = "0.1"
and this to your crate root:
extern crate spiral;
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`. }
