TechCast #92 – Steve Klabnik on Rust


This week, we talk to Rust Core Developer and upcoming Philly Emerging Tech Speaker Steve Klabnik. Steve wrote the Rust guide and contributes to the Rust documentation, and has been a core team member since December of 2014.

Steve will be a speaker at Emerging Technologies for the Enterprise. His talk is called Rust in Production. Learn more about this developer-friendly, Chariot-sponsored conference here.

We Talk to Steve About:

  • How three groups in particular – systems programmers, functional programmers, and dynamic language developers – benefit and are uniquely benefitted by the Rust language.
  • For the systems folks: how Rust is beating the C and C++ teams in terms of speed (it currently has the fastest Regular Expression program).
  • For the dynamic developers: how Rust allows teams to drop down to a low-level language for performance when necessary without the terror of shipping C or C++ code. You get the low-level benefits of C++ and the comfort of Rust checking your work. As Steve puts it, it’s like a good friend looking out for you.
  • For the functional programmers: You can program in a functional style while getting C performance instead of functional language performance. In return, functional folks have brought a deep understanding of type systems and static analysis to Rust that enables high speeds at a low cost.
  • The tooling involved such as Cargo, as well as Rust’s support for VIM, eMacs, and IDE integration.
  • Non-traditional uses of Rust, like compiler extensions. Compiler extensions allow you to invent new syntax in a scoped fashion, and include various features not yet inbuilt to the language itself.
  • Rust’s unique release process. Steve tells us about a mind-blowing tool called Crater, which runs across every open-source Rust package out there and tells the team which versions have failed to compile.
  • How strong conventions help stabilize Rust’s package manager.
  • The awesome names of Rust’s ecosystem: the Rustonomicon (the Dark Arts of Rust Programming), Rustaceans (people who develop on Rust), and Rust’s unofficial mascot, Ferris the Crab (think: Ferrous).
