pub fn try_tls_pem_bundle() -> Option<PemBundle>Expand description
Try to find a usable TLS PemBundle
by probing the same sources as try_tls_acceptor /
try_tls_connector.
Returns the first bundle whose CA certificate is readable.
Only CA readability is checked — cert and key are returned as-is
and may not be valid. Callers that cannot use tokio_rustls types
directly (e.g. reqwest) can read the raw PEM bytes via
Pem::reader.
