A high-performance Rust RPC library that supports multiple transport protocols (TCP, WebSocket, HTTP, RDMA) with unified API, and OpenAPI integration.
- Multiple Transport Protocols: TCP, WebSocket, HTTP, RDMA (optional), and a unified protocol that supports all simultaneously
- Multiple Serialization Formats: JSON (default) and MessagePack support
- OpenAPI Integration: Automatic OpenAPI 3.0 specification generation with JSON Schema support
- Built-in Documentation: RapiDoc integration for interactive API documentation
Define service:
#![feature(return_type_notation)]
use ruapc::{Context, Result};
use schemars::JsonSchema;
use serde::{Deserialize, Serialize};
#[derive(Serialize, Deserialize, Debug, Clone, JsonSchema)]
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();
EchoService::ruapc_export(demo.clone(), &mut router);
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);
}You can directly execute the demo programs provided in ruapc-demo:
# Start the server with unified protocol (supports TCP, WebSocket, and HTTP simultaneously)
cargo run --release --bin server -- --socket-type unified
# Or start with specific protocol
cargo run --release --bin server -- --socket-type tcp
cargo run --release --bin server -- --socket-type ws
cargo run --release --bin server -- --socket-type http# Stress testing with different protocols
cargo run --release --bin client -- --stress --coroutines 128 --secs 10 --socket-type tcp
cargo run --release --bin client -- --stress --coroutines 128 --secs 10 --socket-type ws
cargo run --release --bin client -- --stress --coroutines 128 --secs 10 --socket-type http
# Or use curl to send HTTP requests.
curl -s -X POST -d '"hello HTTP"' http://0.0.0.0:8000/EchoService/echo | json_pp
#> {
#> "Ok" : "hello HTTP"
#> }
curl -s -X POST http://0.0.0.0:8000/MetaService/list_methods | json_pp
#> {
#> "Ok" : [
#> "EchoService/echo",
#> "MetaService/list_methods",
#> "MetaService/openapi",
#> "GreetService/greet"
#> ]
#> }
# Access interactive API documentation
