    /// Readable
    ///
    ///
    /// #### `issuer`
    ///  A #GTlsCertificate representing the entity that issued this
    /// certificate. If [`None`], this means that the certificate is either
    /// self-signed, or else the certificate of the issuer is not
    /// available.

    /// Beware the issuer certificate may not be the same as the
    /// certificate that would actually be used to construct a valid
    /// certification path during certificate verification.
    /// [RFC 4158](https://datatracker.ietf.org/doc/html/rfc4158) explains
    /// why an issuer certificate cannot be naively assumed to be part of the
    /// the certification path (though GLib's TLS backends may not follow the
    /// path building strategies outlined in this RFC). Due to the complexity
    /// of certification path building, GLib does not provide any way to know
    /// which certification path will actually be used. Accordingly, this
