onigiri::tools is the tool of handling chars.
onigiri::validator is validate whether Vec<char> is valid.
Some examples are as follows.
let test_text = "(13 + 2)";
let new_vvchar = onigiri::tools::create_vvchar(&test_text, ' ');
assert_eq!(&new_vvchar, &vec![vec!['(', '1','3'],vec!['+'],vec!['2', ')']]);
let thirteen = &new_vvchar[0][1..].to_vec();
assert_eq!(onigiri::validator::is_positive_integer(&thirteen), true);
let num = onigiri::tools::cast::<u8>(&thirteen);
assert_eq!(&num, &Some(13_u8));
assert_eq!(&num.unwrap() + 2, 15_u8);
