27 * {2 Proxy module around MySQL conection}
29 * The behaviour of this module is influenced by the Helm_registry boolean value
30 * of the "db.nodb" key. When set to "false" the module works as expected. When
31 * set to "true" all functions perform dummy action: connect and disconnect do
32 * nothing; exec, iter, and map work like the empty set of results has been
33 * returned; errno and status return Mysql.Connection_error
45 | GENERIC_ERROR of string
46 exception Error of string
