API

Between::new(chars: Vec<char>) -> Self

Initializes Between with a custom set of characters.

use between::Between;

let between = Between::new(vec!['a', 'b', 'c', 'd', 'e']);

By default, Between uses the following characters to generate strings:

!0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ_abcdefghijklmnopqrstuvwxyz~

between.between(a: String, b: String) -> Option<String>

Generates a string that lexicographically sorts between a and b.

• a must be lexicographically less than b. In other words, a < b.
• a and b can be any string that does not end in the lowest character. this is like how there is only one number between 0 and 1 that ends in a "0".

let tween = between.between(String::from("a"), String::from("b"));

tween is an Option<String> that, if Some, contains a string that will sort between 'a' and 'b'.

between.after(a: String) -> Option<String>

Generate a string that sorts between a and the highest character (between.high()).

The string a cannot begin with the highest character.

between.before(a: String) -> Option<String>

Generate a string that sorts between the lowest character (between.low()) and a.
