#[rustfmt::skip] #

The #[rustfmt::skip] attribute is a directive you can place above a piece of code to tell rustfmt to ignore it during formatting. This is useful when you have a specific formatting style that you want to preserve, which might otherwise be altered by rustfmt.

#[rustfmt::skip]
let data = [
    [1, 2, 3],
    [4, 5, 6],
    [7, 8, 9],
];

In the above example, the #[rustfmt::skip] attribute ensures that the manually formatted array stays in its table-like format.

While rustfmt is great for keeping your codebase consistent, there are times when manual formatting makes the code more readable. For instance, when aligning match arms, or when organizing numerical data in a table-like format.
