Similar to the `@run` decorator, this decorator causes a wrapped method to be retried in the case that the method throws an exception which appears to be caused by a lost connection. While the `@run` decorator is limited to wrapping methods with a particular signature (including `query` and `bindings` params, the `@recoverable` decorator is more generally applicable.

In the event that the connection has been lost, causing an exception when the connection attempts to set the autoconnect mode, the operation should be retried.

Similar to the
@rundecorator, this decorator causes a wrapped method to be retried in the case that the method throws an exception which appears to be due to a lost connection.While the
@rundecorator is limited to wrapping methods with a particular signature (includingqueryandbindingsparams), the@recoverabledecorator is more generally applicable.The
@recoverabledecorator can be applied toMySQLConnection.begin_transaction()in order to provide protection from stale connections in that context.Note that a more direct approach does exist to this problem, as illustrated in #298. I would be most thankful if either approach is adopted!
