Macro rpc_try 

macro_rules! rpc_try {
    ($result:expr, $id:expr) => { ... };
    ($result:expr, $id:expr, $error_code:expr) => { ... };
    ($result:expr, $id:expr, $error_code:expr, $message:expr) => { ... };
}

Convert Result types to JSON-RPC responses with error logging

This macro logs detailed errors server-side and returns a generic error. For custom error messages, provide them explicitly.

Usage:

rpc_method!(DivideMethod, "divide", |params, id| {
    let [a, b]: [f64; 2] = rpc_params!(params, id => [f64; 2]);
    let result = if b != 0.0 { Ok(a / b) } else { Err("Division by zero") };
    rpc_try!(result, id)
});
