Rust is a systems programming language. It aims for there to be as little as possible between your code and the hardware running it. The reason for this is to give you full control of what the CPU is doing, and how your data structures are laid out in memory.
I’ve been listening to the Lambdacast podcast recently. During one episode they had a discussion about algebraic data types and the differences between product and sum types. I’d heard the term algebraic data types before, but had no idea what product or sum types are. I figured I should spend some time reading up about them.
