BUS/RT - Rust-native IPC broker

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.

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.
