Expand description

JSON-RPC client interface that can make requests, notifications and subscriptions.

Required Methods§

Initiate a subscription by performing a JSON-RPC method call where the server responds with a Subscription ID that is used to fetch messages on that subscription,

The subscribe_method and params are used to ask for the subscription towards the server.

The params may be used as input for the subscription for the server to process.

The unsubscribe_method is used to close the subscription

The Notif param is a generic type to receive generic subscriptions, see Subscription for further documentation.

Register a method subscription, this is used to filter only server notifications that a user is interested in.

The Notif param is a generic type to receive generic subscriptions, see Subscription for further documentation.
