Expand description

Pad all values in a collection to be of same (maximum) width.

Required features: std

Key traits:

Example:

use zero_copy_pads::{PaddedColumn, AlignRight};
let values = vec![
    "Rust", "C", "C++", "C#", "JavaScript",
    "TypeScript", "Java", "Kotlin", "Go",
];
let padded_column = PaddedColumn {
    values: values.iter(),
    pad_block: ' ',
    pad: AlignRight,
};
let padded_values: Vec<_> = padded_column
    .into_iter()
    .map(|x| x.to_string())
    .collect();
let expected = [
    "      Rust", "         C", "       C++",
    "        C#", "JavaScript", "TypeScript",
    "      Java", "    Kotlin", "        Go",
];
assert_eq!(padded_values, expected);
