A newbie question. As a seasoned C#, Python and JS programmer, what conceptual foundations in CS will make me use rust more effectively? Say I want to create a new database service, on top of Postgresql, using rust. Would the design of rust help me in a specific way? I want to learn and use rust, for systems programming, the kind where I build a high performance underlying system, called by other languages, but it always feels I need to learn quite a bit of theory to effectively use rust. I never felt the same with C# or python. A bit of OO stuff was usually enough to be productive with them.
