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.

[@01:25] - What is yours (and Embark’s) background in game development?

[@02:14] - What is the relevance of the Frostbite engine and what is your experience with it?

[@04:15] - What makes you think that Rust as a language is suitable for game development?

[@06:13] - How is parallelism employed in a game engine on the scale of Frostbite?

[@07:07] - Where is the Rust library ecosystem lacking for your use case, and what crates are you making use of?

[@11:13] - Why is Embark interested in WebAssembly?
