Function strsim::generic_jaro_winkler

pub fn generic_jaro_winkler<'a, 'b, Iter1, Iter2, Elem1, Elem2>(
    a: &'a Iter1, 
    b: &'b Iter2
) -> f64 where
    &'a Iter1: IntoIterator<Item = Elem1>,
    &'b Iter2: IntoIterator<Item = Elem2>,
    Elem1: PartialEq<Elem2>, 

Like Jaro but gives a boost to sequences that have a common prefix.
