Summary of RustConf 2022 - All aboard the Rust (electric freight) train! by Julie Wang

00:00:00 - 00:30:00

Julie Wang discusses the successes and failures of using Rust in vehicle software development. She describes how state machine diagrams generated by Rust helped them overcome challenges. The video also covers how to use Rust's foreign function interface to bring in C code without additional runtime cost.

• 00:00:00 In this talk, Julie Wang discusses the successes and failures of using Rust in vehicle software. She describes how the language features helped them overcome challenges such as organizing the code into state machines, and making it easy to create new state machines.
• 00:05:00 RustConf 2022 discusses the Rust language's ability to generate state machine diagrams automatically, which is a huge advantage over traditional development methods. These diagrams can be incredibly helpful in debugging and communicating between software and hardware engineers.
• 00:10:00 This video introduces the RustConf 2022 talk "All aboard the Rust (electric freight) train!," which discusses the development of a vehicle simulation system in Rust. The system is organized into three layers: the hardware abstraction layer, the software under test (UTT) layer, and the conductor layer. Traits are used to provide a uniform interface to nodes in the UTT layer, and the performance of generics is compared to that of function calls with structs.
• 00:15:00 In this video, Julie Wang demonstrates how Rust can be used to create a physics-based simulation. She covers how to create an enum to represent nodes on a network, how to implement the node trait for the enum, and how to use enum dispatch to generate code for handling the packets sent between nodes. Additionally, she covers how Rust helps manage the complexity of the railway network.
• 00:20:00 RustConf 2022 features a discussion on the development of a Fleet Management System using Rust. The system employs primitive types to encode and decode message types from Positive Train Control, and a custom derived macro to annotate structs. The system also makes extensive use of rust macros to speed up development and allow the engineer to focus on getting the structs right. Finally, the presentation discusses the use of deep learning for detecting and localizing Hazards around the rail.
• 00:25:00 RustConf 2022 discusses how to use existing libraries from Nvidia while still writing the bulk of an application in Rust. Crabification is a process of taking a perception application from Cedar, a C++ library, and converting it into a Rust library that uses bindings to the C libraries. The talk also covers how to create a user-friendly API for the C libraries and how to ensure safety and correctness in the code.
• 00:30:00 In this video, Julie Wang describes RustConf 2022, a conference on the programming language Rust. The video covers the basics of Rust, including its safety features and its use of macros. It also covers how to use Rust's foreign function interface to bring in C code without additional runtime cost.
