kazoo.interfaces
IHandler implementations should be created by the developer to be passed into ~kazoo.client.KazooClient during instantiation for the preferred callback handling.
If the developer needs to use objects implementing the IAsyncResult interface, the IHandler.async_result method must be used instead of instantiating one directly.
IHandler
The IAsyncResult documents the proper implementation for providing a value that results from a Zookeeper completion callback. Since the ~kazoo.client.KazooClient returns an IAsyncResult object instead of taking a completion callback for async functions, developers wishing to have their own callback called should use the IAsyncResult.rawlink method.
