RustFest Interviews Triple Feature: Rust for AAA Game Development; Async Foundations with `async-std`; and Powerful Concurrency Primitives with `crossbeam`

Posted Wed, 22 Jan 2020 23:30:00 +0000 Discussion on Reddit

Three more interviews from RustFest 2019: Jake Shadle on using Rust for high-performance game engines at Embark, applying lessons learned from working on EA DICE’s Frostbite engine; Yoshua Wuyts on async-std and Rust’s async ecosystem; and Stjepan Glavina on crossbeam, Rust’s foundational library for powerful concurrency primitives.

[@15:09] Part 2: async-std w/ Yoshua Wuyts

  • [@15:48] - How much of the Rust standard library is async-std intended to emulate?
