    cert: &ParsedCertificate<'_>,

) -> Result<(), Error>Expand description
Verify that the end-entity certificate end_entity is a valid server cert
and chains to at least one of the trust anchors in the roots RootCertStore.
This function is primarily useful when building a custom certificate verifier. It
performs no revocation checking. Implementors must handle this themselves,
along with checking that the server certificate is valid for the subject name
being used (see verify_server_name).
intermediates contains all certificates other than end_entity that
were sent as part of the server’s Certificate message. It is in the
same order that the server sent them and may be empty.
