+///
+/// Redis permits only a single module info callback. When this crate is
+/// embedded into a host C module, the host owns that callback so it can also
+/// report its own metrics; the dispatcher registered by the generated
+/// `RedisModule_OnLoad` (renamed to `LDAP_OnLoad`) is therefore overwritten.
+/// The host invokes this shim from its own callback so the LDAP INFO sections
+/// are still emitted.
