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

Required Methods

fn subscribe<'a, 'life0, 'async_trait, Notif, Params>( &'life0 self, subscribe_method: &'a str, params: Params, unsubscribe_method: &'a str, ) -> Pin<Box<dyn Future<Output = Result<Subscription<Notif>, Error>> + Send + 'async_trait>>

where Params: ToRpcParams + Send + 'async_trait, Notif: DeserializeOwned + 'async_trait, Self: 'async_trait, 'a: 'async_trait, 'life0: 'async_trait,

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.

fn subscribe_to_method<'a, 'life0, 'async_trait, Notif>( &'life0 self, method: &'a str, ) -> Pin<Box<dyn Future<Output = Result<Subscription<Notif>, Error>> + Send + 'async_trait>>

where Notif: DeserializeOwned + 'async_trait, Self: 'async_trait, 'a: 'async_trait, 'life0: 'async_trait,

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.
