Function console::truncate_str

pub fn truncate_str<'a>(s: &'a str, width: usize, tail: &str) -> Cow<'a, str>

Truncates a string to a certain number of characters.

This ensures that escape codes are not screwed up in the process. If the maximum length is hit the string will be truncated but escapes code will still be honored. If truncation takes place the tail string will be appended.
