# Examples
This is a basic example with two methods:
```rust
#[macro_use(rpc_method)]
extern crate json_rpc;
use json_rpc::{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();
match rpc_server.request(str_request) {
Some(str_response) => assert_eq!(str_response, "{\"id\":2,\"jsonrpc\":\"2.0\",\"result\":19}") ,
None => unreachable!(),
};
let str_request = "{\"jsonrpc\":\"2.0\",\"method\":\"Multiply\", \"params\":[5, 6, 7], \"id\":3}".to_string();
match rpc_server.request(str_request) {
Some(str_response) => assert_eq!(str_response, "{\"id\":3,\"jsonrpc\":\"2.0\",\"result\":210}") ,
None => unreachable!(),
};
}
```
