pub fn count_words(words: &[String]) -> HashMap<String, u32>

Takes &Vec and counts the quantity of each word. Returns Hashmap<String,u32>, with String being the word and u32 the quantity

Example

#[test]
fn test_count_words() {
use text_analysiss::count_words;
let words = vec![
           "one".to_string(),
           "two".to_string(),
           "two".to_string(),
           "three".to_string(),
           "three".to_string(),
           "three".to_string(),
       ];
       let counted = count_words(&words);
       let mut words_map = HashMap::new();
       words_map.insert("one".to_string(), 1 as u32);
       words_map.insert("two".to_string(), 2 as u32);
       words_map.insert("three".to_string(), 3 as u32);
       assert_eq!(counted, words_map);
