What is this

This is a macro for RPC programming needs which generates a structure and a thunk for function in a way that allows calling that function with a struct argument that supports serde::Deserialize

How to use

1. Mark function with #[server_function] attribute

   ```rust

   [server_function]

   fn add(a: u32, b: u32) -> u32 { a + b } ```

2. This will generate AddArgs struct matching your function arguments that looks like this

   rust struct AddArgs { a: u32, b: u32 }

   and a function named add_thunk with AddArgs struct as 1 argument

3. Now you can call it

   rust // will return 10, same as original function add_thunk(AddArgs { a: 5, b: 5 })
