json rpc

JSON-RPC 2.0 Implementation in Rust

|Crate|Travis| |:------:|:-------:| |||

Currently in development.

Examples

This is a basic example with two methods:

```rust

[macrouse(rpcmethod)]

extern crate jsonrpc; use jsonrpc::{Server, Json, Error};

fn main() { let mut rpc_server = Server::new();

// Registers a Rpc Method named "Subtract" with two parameter "by Name".
rpc_method!(rpc_server, Subtract, oper1<u64>;oper2<u64>, {                
    Ok(Json::U64(oper1 - oper2))        
});

// Registers a Rpc Method named "Multiply" with N parameteres "by Position".
rpc_method!(rpc_server, Multiply, values[u64], {        
    let mut r = 1;
    for v in values { r *= v }
    Ok(Json::U64(r))
});    

let str_request = "{\"jsonrpc\":\"2.0\",\"method\":\"Subtract\", \"params\":{\"oper1\":23, \"oper2\":4}, \"id\":2}".to_string();
rpc_server.request(str_request, |str_response| {
    assert_eq!(str_response, "{\"id\":2,\"jsonrpc\":\"2.0\",\"result\":19}");
});

let str_request = "{\"jsonrpc\":\"2.0\",\"method\":\"Multiply\", \"params\":[5, 6, 7], \"id\":3}".to_string();
rpc_server.request(str_request, |str_response| {
    assert_eq!(str_response, "{\"id\":3,\"jsonrpc\":\"2.0\",\"result\":210}");
});

}
