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.
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
- Dart https://github.com/AndreiLosev/busrt_client
Rust crate: https://crates.io/crates/busrt
Use rt feature to use for internal mutexes
parking_lot_rt - a parking_lot
fork without spin-locks, which is real-time safe.
