How to Use the Standard Sync Module With Cross Beam Pointer?

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.
