Textwrap crate - example

Runnable project

Example of textwrap fill and wrap:

use textwrap::{fill, wrap};

fn main() {
    let s = "Rust is a great programming language for us";
    println!("{}", fill(s, 22));
    println!("{:?}", wrap(s, 22));
}

Example output:

Rust is a great
programming language
for us
["Rust is a great", "programming language", "for us"]

In this example, we import the fill and wrap functions from the textwrap crate.

We use fill to fill one string with lines that are each 22 characters maximum per line.

We use wrap to create a vector of strings that are each 22 characters maximum per line.
