Macro grid::grid

macro_rules! grid {
    () => { ... };
    ([$($x : expr), *]) => { ... };
    ([$($x0 : expr), *] $([$($x : expr), *]) *) => { ... };
}

Init a grid with values.

Each array within [] represents a row starting from top to button.

Examples

In this example a grid of numbers from 1 to 9 is created:

use grid::grid;
let grid = grid![[1, 2, 3]
[4, 5, 6]
[7, 8, 9]];
assert_eq!(grid.size(), (3, 3))

Examples

Not that each row must be of the same length. The following example will not compile:

use grid::grid;
let grid = grid![[1, 2, 3]
[4, 5] // This does not work!
[7, 8, 9]];
