Function did_you_mean

pub fn did_you_mean<T, I>(v: &str, candidates: I) -> Vec<String>
where
    T: AsRef<str>,
    I: IntoIterator<Item = T>,

Filters multiple strings from a given list of possible values which are similar to the passed in value v within a certain confidence by least confidence.

The jaro winkler similarity boosts candidates that have a common prefix, which is often the case in the event of typos. Thus, in a list of possible values like [“foo”, “bar”], the value “fop” will yield Some("foo"), whereas “blark” would yield None.
