Contributors About the author Carl Fredrik Samson is a popular technology writer and has been active in the Rust community since 2018. He has an MSc in Business Administration where he specialized in strategy and finance. When not writing, he's a father of two children and a CEO of a company with 300 employees. He's been interested in different kinds of technologies his whole life and his programming experience ranges from programming against old IBM mainframes to modern cloud computing, using everything from assembly to Visual Basic for Applications. He has contributed to several open source projects including the official documentation for asynchronous Rust. I want to thank the Rust community for being so constructive, positive and welcoming. This book would not have happened had it not been for all the positive and insightful interaction with the community. A special thanks goes to the implementors of all the libraries that underpins the async ecosystem today like mio, Tokio, and async-std. I also want to thank my editor, Kinnari, who has been extraordinarily patient and helpful during the process of writing this book.
