xRPC-rs

Fast RPC library for Rust with multiple transport implementations.

This library provides efficient message passing with various transports including in-process channels, shared memory for IPC, and planned support for network transports (TCP, etc.). While currently focused on local communication, the architecture is designed to support both local and remote RPC scenarios.

Status: Very early prototype - It is working but not production-ready.

Architecture

xRPC follows a layered architecture:

• Layer 1: Transport - Low-level byte transmission (TCP, Unix, UDP, SharedMemory, Channel)
• Layer 2: Message - Protocol format with serialization/deserialization
• Layer 3: Compression/Streaming - Optional transport wrappers (Not implemented yet)
• Layer 4: Client/Server - Message-aware RPC with method dispatch (Not implemented yet)

Documentation

• Message Protocol - Binary message format specification

Future Plans

Completed

• Add support for streaming & compression on message
• Transport layer abstraction
• Local Channel Transport implementation
• SharedMemory Transport implementation
• Heartbeat abstraction for transport reliability
• RawTransport (skip Message protocol overhead)
• ArcTransport (Arc-based, no serialization)

Refactoring Tasks

• Module reorganization: Split protocol.rs into message module.
• Codec trait abstraction: Decouple serialization format
• Relocate TypedChannel

Planned Features

• Network transports
  • TCP Transports
  • UDP Transports
  • Unix socket Transports
• Examples for Transports
• Compression wrapper for transports (integrating Message)
• Streaming support
• Documentation for Transports
• High-level Client/Server architecture
• Batching support
• Service Discovery & Load Balancing
