A small utility to split a string into the first character (type char) and the rest (type &str).
rust
use split_first_char::split_first_char;
let (first_char, rest) = split_first_char("abc").unwrap();
assert_eq!(first_char, 'a');
assert_eq!(rest, "bc");
rust
use split_first_char::SplitFirstChar;
let (first_char, rest) = "abc".split_first_char().unwrap();
assert_eq!(first_char, 'a');
assert_eq!(rest, "bc");
If you don't need the first character to be a char, just use str.split_at(1), it will return a tuple of 2 strings.
