Function link 

pub fn link<'a, E>(
    input: &'a str,
) -> Result<Vec<Option<LinkData<'a>>>, LinkParseError>
where
    E: ParseError<&'a str>,
    Err<VerboseError<&'a str>>: From<Err<E>>,

👎Deprecated since 0.4.0: please use link_strict instead

Same as link_strict, but with the original name. When lenient parsing was introduced, to avoid ambiguity the function was renamed. To avoid breakages, the function still exists, but instead use link_strict.
