A high-performance RPC framework for Rust with support for shared memory, TCP, WebSocket, and in-process transports.
## Features
- **Multiple transports**: Choose the right transport for your use case
- Shared memory (SHM): Ultra-low latency for local processes
- TCP/Unix sockets: Network communication
- WebSocket: Browser and web clients
- In-memory: Testing and single-process RPC
- **Streaming**: Full support for server and client streaming
- **Code generation**: Write your service interface once with `#[rapace::service]`
- **Type-safe**: Compile-time verification of RPC calls
- **Cross-platform**: Linux, macOS, Windows, and WebAssembly
## Quick Start
```rust
use rapace::service;
use rapace::RpcSession;
use rapace_transport_mem::MemTransport;
#[rapace::service]
pub trait Calculator {
async fn add(&self, a: i32, b: i32) -> i32;
}
// Implement your service...
struct MyCalculator;
impl Calculator for MyCalculator {
async fn add(&self, a: i32, b: i32) -> i32 {
a + b
}
}
// Use it with any transport
let (client_transport, server_transport) = MemTransport::pair();
let session = RpcSession::new(client_transport);
let client = CalculatorClient::new(session);
```
