A collection of anagram utility functions
```rust use anagram::{count, getnext, isanagram, occurences};
fn main() { // count how many anagrams can be formed from a given word let anagramcount = count("ordeals"); asserteq!(anagram_count, 5040);
// count the number of occurences of an anagram in a given word let occur = occurences("helloworldhello", "ll"); assert_eq!(occur, 2);
// check if a word is an anagram of another word let ok = isanagram("rustiscool", "oolcsistru"); asserteq!(ok, true);
// get the next lexicographically greater anagram let next = getnext("abcdefg"); asserteq!(next, "abcdegf");
// get all anagrams of a word let mut word: String = String::from("abc"); for _ in 0..count(&word) { // get next anagram word = get_next(&word); println!("{}", word); } } ```
