Remove Characters From The End Of A String In Rust

fn main() {
    let source = "alfabravocharlie";
    let chopped = source.get(0..4).unwrap();
    println!("{}", chopped);
}

Output:

alfa

Notes

This is really making a new string with just the selected characters from the beining of the source string, but that's too long for a title
I genearlly think of this as truncating, but that means completely deleting in some contexts
This is like a substring in some other langauges. Should probably rename the title to that at some point
