Note: This site is currently "Under construction". I'm migrating to a new version of my site building software. Lots of things are in a state of disrepair as a result (for example, footnote links aren't working). It's all part of the process of building in public. Most things should still be readable though.

Remove Characters From The End Of A String In Rust

Code

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

Results

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
