Crate rapace 

rapace

High-performance RPC framework with support for multiple transports (shared memory, TCP, WebSocket) and streaming.

Features

• Multiple transports: In-process (mem), TCP/Unix socket (stream), WebSocket, and shared memory (SHM)
• Streaming: Full support for server and client streaming RPC calls
• Code generation: Automatic client and server code generation from trait definitions
• Zero-copy: Shared memory transport for ultra-low latency
• Cross-platform: Works on Linux, macOS, Windows, and WebAssembly

Quick Start

use rapace::service;

#[rapace::service]
pub trait Calculator {
    async fn add(&self, a: i32, b: i32) -> i32;
    async fn multiply(&self, a: i32, b: i32) -> i32;
}
