iter-grid

Ideomatic Grid operations via Iterators

The grid-iter crate provides convenient methods to wrap a flat iterator and perform operations on it as if it was a grid.

lib.rs:

Grids for Iterators

Provides a two dimensional abstraction over Iterators. Intended to be simple, flexible and ideomatic.

use grid_iter::IntoGridIter;

let file:&str = "1,2,3,4,5\n6,7,8,9,10\n11,12,13,14,15";
let columns = file.find('\n').unwrap();
let mut store = file.lines()
    .flat_map(|line|line.split(',').map(|s|s.parse().unwrap()))
    .collect::<Vec<_>>();
store.iter_mut().into_grid_iter(columns).iter_col(3).for_each(|i| *i= 0);
store.iter_mut().into_grid_iter(columns).iter_row(1).for_each(|i| *i+= 1);
let borrowing_grid = store.iter().into_grid_iter(5);
drop(borrowing_grid);
let capturing_grid = store.iter().into_grid_iter(5);
println!("{:?}", capturing_grid);
