RuaPC

A Rust RPC library.

Example

Define service:

#![feature(return_type_notation)]

use ruapc::{Context, Result};
use serde::{Deserialize, Serialize};

#[derive(Serialize, Deserialize, Debug, Clone)]
pub struct Request(pub String);

#[ruapc::service]
pub trait EchoService {
    async fn echo(&self, c: &Context, r: &Request) -> Result<String>;
}

Start server:

use ruapc::*;
use ruapc_demo::{EchoService, Request};
use std::{net::SocketAddr, str::FromStr, sync::Arc};

struct DemoImpl;

impl EchoService for DemoImpl {
    async fn echo(&self, _c: &Context, r: &Request) -> Result<String> {
        Ok(r.0.clone())
    }
}

#[tokio::main]
async fn main() {
    let demo = Arc::new(DemoImpl);
    let mut router = Router::default();
    router.add_methods(EchoService::ruapc_export(demo.clone()));
    let server = Server::create(router, &SocketPoolConfig::default());

    let server = Arc::new(server);
    let addr = SocketAddr::from_str("127.0.0.1:8000").unwrap();
    let addr = server.listen(addr).await.unwrap();
    println!("Serving on {addr}...");
    server.join().await
}

Make a request:

use ruapc::*;
use ruapc_demo::{EchoService, Request};
use std::{net::SocketAddr, str::FromStr};

#[tokio::main]
async fn main() {
    let addr = SocketAddr::from_str("127.0.0.1:8000").unwrap();
    let ctx = Context::create(&SocketPoolConfig::default()).with_addr(addr);
    let client = Client::default();

    let rsp = client.echo(&ctx, &Request("Rua!".into())).await;
    println!("echo rsp: {:?}", rsp);
}
