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§
- An iterator iterating in a spiral fashion with the Chebyshev distance function.
- An iterator iterating in a spiral fashion with the Manhattan distance function.
Traits§
- Simple trait so we don’t have to wrap write all the num signatures that we want every time.
