At Parallel Systems, a team of C++ and Python developers raised on null pointers, read/write races, and the wild west of pip packaging, set off to create a modern electric freight train with an appropriately modern systems language – Rust. We dive into our use of Rust as a general-purpose language for our entire tech stack for a safety-critical, real-time application. Join us to learn about how we use Rust to write firmware, to control and simulate the freight vehicle, and even to wrap deep learning libraries to make them all available in Rust.
