susydev-jsonrpc-macros 10.0.1

High level, typed wrapper for susydev_jsonrpc_core.

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

Example

extern crate susydev_jsonrpc_core;
#[macro_use] extern crate susydev_jsonrpc_macros;
use susydev_jsonrpc_core::{IoHandler, Error, Result};
use susydev_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());
}
