-# subxt-rpcs
-
-This crate provides an interface for interacting with Substrate nodes via the available RPC methods.
-
-```rust
-use subxt_rpcs::{RpcClient, ChainHeadRpcMethods};
-
-// Connect to a local node:
-let client = RpcClient::from_url("ws://127.0.0.1:9944").await?;
-// Use a set of methods, here the V2 "chainHead" ones:
-let methods = ChainHeadRpcMethods::new(client);
-
-// Call some RPC methods (in this case a subscription):
-let mut follow_subscription = methods.chainhead_v1_follow(false).await.unwrap();
-while let Some(follow_event) = follow_subscription.next().await {
-    // do something with events..
-}
-```
