pub fn set_cluster_tls(tls: ClusterTls) -> Result<(), String>Expand description
Install process-wide control-plane TLS before any cluster transport is constructed.
Reinstalling byte-identical material is idempotent. Different material, or installation after plaintext was explicitly selected or used by a transport, fails closed.
ยงErrors
Returns an error when transport mode is already plaintext or different TLS material is active.
