Shared JSON-RPC client related code and abstractions.

It exposes a WebSocket JSON-RPC client that implements the RPC interface in sc-rpc-api along with some abstractions.

Usage

#[tokio::main]
async fn main() {

    let client = ws_client("ws://127.0.0.1:9944").await.unwrap();
    client.storage(StorageKey(vec![]), Some(H256::zero())).await.unwrap();

    // if all type params are not known you need to provide type params
    StateApi::<H256>::storage(&client, StorageKey(vec![]), None).await.unwrap();
}
