BUS/RT - Rust-native IPC broker crates.io page docs.rs page GitHub Actions CI

What is BUS/RT

BUS/RT® is a Rust-native IPC broker, written in Rust/Tokio, inspired by NATS, ZeroMQ and Nanomsg. 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 standalone server.

BUS/RT is the core bus of EVA ICS v4.

Inter-process communication

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:

Rust crate: https://crates.io/crates/busrt

Real-time safety

Use rt feature to use for internal mutexes parking_lot_rt - a parking_lot fork without spin-locks, which is real-time safe.
