What is Rust and why would you use it with C#? While at NDC in Oslo, Carl and Richard chatted with Ashley Mannix about he and the team at Datalust build Seq, a structured log server, using Rust on the back end and C# on the front. Rust looks a lot like C++, but with a great type safety system and a smart compiler that can help catch memory leaks before they happen. Rust is a modern language with modern capabilities and well worth the look!
