/src/rpc_server.rs

//! implements an RPC server and client based on [tarpc]
//!
//! request and response data is json serialized.
//!
//! It is presently easiest to create a tarpc client in rust.
//! To do so, one should add neptune-cash as a dependency and
//! then do something like:
//!
//! ```no_run
//! use anyhow::Result;
//! use neptune_cash::rpc_server::RPCClient;
//! use neptune_cash::rpc_auth;
//! use tarpc::tokio_serde::formats::Json;
//! use tarpc::serde_transport::tcp;
//! use tarpc::client;
//! use tarpc::context;
//!
//! # #[tokio::main]
//! # async fn main() -> Result<()>{
//! // create a serde/json transport over tcp.
//! let transport = tcp::connect("127.0.0.1:9799", Json::default).await?;
//!
//! // create an rpc client using the transport.
//! let client = RPCClient::new(client::Config::default(), transport).spawn();
//!
//! // query neptune-core server how to find the cookie file
//! let cookie_hint = client.cookie_hint(context::current()).await.unwrap().unwrap();
//!
//! // load the cookie file from disk and assign it to a token.
//! let token: rpc_auth::Token = rpc_auth::Cookie::try_load(&cookie_hint.data_directory).await?.into();
//!
//! // query any RPC API, passing the auth token.  here we query block_height.
//! let block_height = client.block_height(context::current(), token).await??;
//! # Ok(())
//! # }
//! ```
//!
//! For other languages, one would need to connect to the RPC TCP port and then
//! manually construct the appropriate json method call.  Examples of this will
//! be forthcoming in the future.
//!
//! See [rpc_auth] for descriptions of the authentication mechanisms.
//!
//! Every RPC method returns an [RpcResult] which is wrapped inside a
//! [tarpc::Response] by the rpc server.
