Async::Bus

When building distributed systems or multi-process applications, you need a way for processes to communicate and invoke methods on objects in other processes. async-bus provides a lightweight message-passing system for inter-process communication (IPC) using Unix domain sockets, enabling transparent remote procedure calls (RPC) where remote objects feel like local objects.

Use async-bus when you need:

Inter-process communication: Connect multiple Ruby processes running on the same machine.
Transparent RPC: Call methods on remote objects as if they were local.
Type-safe serialization: Automatically serialize and deserialize Ruby objects using MessagePack.
Asynchronous operations: Non-blocking message passing built on the Async framework.

Usage

Please browse the source code index or refer to the guides below.

Getting Started

This guide explains how to get started with async-bus to build asynchronous message-passing systems with transparent remote procedure calls in Ruby.

Controllers

This guide explains how to use controllers in async-bus to build explicit remote interfaces with pass-by-reference semantics, enabling bidirectional communication and shared state across connections.
