About the Author Bastian Gruber is a Protocol Engineer at Centrifuge. He was part of the official Rust Async Working Group, and founded the Rust and Tell Berlin MeetUp group. Quotes I always assumed Rust was strictly for areas where I'd use C/C++. This book changed my mind! By the end, I was coding as quickly as I could in JS/Node, but with all the protection of a compiled and type-safe language. I'm a convert! - JD McCormack, Meta Walk with a master as he guides you down the path of creating fast, rock-solid, modern web applications. I would not have thought Rust was well-suited for this. Now I'm looking forward to it. - Christoph Baker, Accenture Industry X A gem for those picking up Rust and struggling. It fills in the blanks where many tutorials fall short. In the end, you'll have a working restful API that you can extend to do your bidding and a solid understanding of how it works. - Walt Stoneburner, Bogart Associates of Northern Virginia Rust Web
