pub fn new(input: &str) -> Result<Self, NamespaceError> {

        match Uri::from_str(input) {

            Ok(uri) => Ok(Self(uri)),

            Err(err) => Uri::from_str(&format!("https://{input}"))

                .map_err(|_| NamespaceError::InvalidUri(err))

                .map(Self),

        }

    }

I don't think we would expose the ErrorKind enum publicly, because it prevents adding new variants, or changing them around
