This library provides general iterator for enumerating Rectangle.
There are many libralies handle 2D rectangle area, so I think it's convinient if we can use those libraries in the same way.
with image feature:
rust
extern crate rect_iter;
extern crate euclid;
use euclid::TypedVector2D;
use rect_iter::{RectRange, FromTuple2, GetMut2D};
type MyVec = TypedVector2D<u64, ()>;
fn main() {
let range = RectRange::from_ranges(4..9, 5..10).unwrap();
let mut buffer = vec![vec![0.0; 100]; 100];
range.iter().for_each(|t| {
let len = MyVec::from_tuple2(t).to_f64().length();
*buffer.get_mut_p(t) = len;
});
}
