Function zxcvbn::zxcvbn

pub fn zxcvbn(
    password: &str, 
    user_inputs: &[&str]
) -> Result<Entropy, ZxcvbnError>

Takes a password string and optionally a list of user-supplied inputs (e.g. username, email, first name) and calculates the strength of the password based on entropy, using a number of different factors.

Currently zxcvbn only supports ASCII input. Non-ASCII passwords can generally be considered to be safe, if they are of a reasonable length (8+ chars), so you should handle them as strong passwords, but this library is not able to generate entropy information for them at this time.
