BUS/RT® is a Rust-native IPC broker, written in Rust/Tokio, inspired byNATS,ZeroMQ andNanomsg. BUS/RT is fast, flexible and very easy to use,optimized for both high-load and ultra-low latency real-time scenarios.

The library can be embedded in any Rust project or be used as a standaloneserver.

BUS/RT is the core bus ofEVA ICS v4.

The following communication patterns are supported out-of-the-box:

• one-to-one messages
• one-to-many messages
• pub/sub

The following channels are supported:

• async channels between threads/futures (Rust only)
• UNIX sockets (local machine, Linux/BSD)
• TCP sockets (Linux/BSD/Windows)

In addition to Rust, BUS/RT has also bindings for the following languages:

• Python (sync):https://pypi.org/project/busrt/
• Python (async):https://pypi.org/project/busrt-async/
• JavaScript (Node.js):https://www.npmjs.com/package/busrt
• Darthttps://github.com/AndreiLosev/busrt_client
