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

   #[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

   struct AddArgs {
       a: u32,
       b: u32
   }

   and a function named add_thunk with AddArgs struct as 1 argument

3. Now you can call it

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

Features

messagepack

Enables rmp-serde and allows server function to be called using raw messagepack bytes using with_bytes_thunk(bytes: &[u8])

Example

let bytes = rmp_serde::to_vec(AddArgs { a: 5, b: 5 }).unwrap();
add_messagepack_thunk(&bytes) // should return 10
