statement_unstable_unsubscribe
Parameters:
subscription: An opaque string that was returned bystatement_unstable_subscribe.
Return value: null
Stops a subscription started with statement_unstable_subscribe. Has no effect if the subscription is invalid or refers to a subscription that has already emitted a {"event": "stop"} event.
Removing a subscription automatically removes all the filters that were attached to it.
JSON-RPC client implementations must be aware that, due to the asynchronous nature of JSON-RPC client <-> server communication, they might still receive statement_unstable_subscribeEvent notifications, for example because these notifications were already in the process of being sent back by the JSON-RPC server.
