Struct zero_copy_pads::PaddedColumn

pub struct PaddedColumn<ValueIter, PadBlock = char, Pad = Alignment> where
    ValueIter: Iterator,
    ValueIter::Item: Width,
    PadBlock: Display + Copy,
    Pad: Pad<ValueIter::Item, PadBlock> + Copy,  {
    pub values: ValueIter,
    pub pad_block: PadBlock,
    pub pad: Pad,
}

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

Required features: std

Key traits:

• IntoIterator: Build an iterator of padded values.

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);

Fields

values: ValueIter

Values to be padded.

pad_block: PadBlock

Block of the pad (expected to have width of 1).

pad: Pad

Where to place the pad.
