Lib.rs

High level, typed wrapper for susy_jsonrpc_core.

Enables creation of "Service" objects grouping a set of RPC methods together in a typed manner.

Example

extern crate susy_jsonrpc_core;
#[macro_use] extern crate susy_jsonrpc_macros;
use susy_jsonrpc_core::{IoHandler, Error, Result};
use susy_jsonrpc_core::futures::future::{self, FutureResult};
build_rpc_trait! {
	pub trait Rpc {
		/// Returns a protocol version
		#[rpc(name = "protocolVersion")]
		fn protocol_version(&self) -> Result<String>;

		/// Adds two numbers and returns a result
		#[rpc(name = "add")]
		fn add(&self, u64, u64) -> Result<u64>;

		/// Performs asynchronous operation
		#[rpc(name = "callAsync")]
		fn call(&self, u64) -> FutureResult<String, Error>;
	}
}
struct RpcImpl;
impl Rpc for RpcImpl {
	fn protocol_version(&self) -> Result<String> {
		Ok("version1".into())
	}

	fn add(&self, a: u64, b: u64) -> Result<u64> {
		Ok(a + b)
	}

	fn call(&self, _: u64) -> FutureResult<String, Error> {
		future::ok("OK".to_owned()).into()
	}
}

fn main() {
     let mut io = IoHandler::new();
     let rpc = RpcImpl;

     io.extend_with(rpc.to_delegate());
}
