I am trying to format a &str into a field that is exactly 7 "characters" wide. I could do the following:

fn fixed_size(inp: &str) -> String {
   let result = inp.to_string();
   result.truncate(7);
   format!("{result:<7}")
}

but (1) that's not exactly right with unicode and (2) seems way more convoluted than it needs to be
