Crate mill_rpc 

Mill-RPC: An Axum-inspired RPC framework built on Mill-IO.

Quick Start

// Define a service — generates a `calculator` module
mill_rpc::service! {
    service Calculator {
        fn add(a: i32, b: i32) -> i32;
    }
}

// Server side
struct MyCalc;
impl calculator::Service for MyCalc {
    fn add(&self, _ctx: &RpcContext, a: i32, b: i32) -> i32 { a + b }
}

// Register
RpcServer::builder()
    .service(calculator::server(MyCalc))
    .build(&event_loop)?;

// Client side
let client = calculator::Client::new(transport, codec, 0);
client.add(2, 3)?;
