Crate jsonrpc_core

Transport agnostic jsonrpc library.

Right now it supports only server side handling requests.

use jsonrpc_core::*;
use jsonrpc_core::futures::Future;

fn main() {
	let mut io = IoHandler::new();
	io.add_method("say_hello", |_| {
		Ok(Value::String("Hello World!".into()))
	});

	let request = r#"{"jsonrpc": "2.0", "method": "say_hello", "params": [42, 23], "id": 1}"#;
	let response = r#"{"jsonrpc":"2.0","result":"Hello World!","id":1}"#;

	assert_eq!(io.handle_request(request).wait().unwrap(), Some(response.to_string()));
}
