[[wikipedia:Rust_(programming_language)|Rust]] is a modern successor of [[C]] - a low level ''system'' programming language without [[Garbage Collection]], but with memory safety! That safety comes from a strict ''linear'' type system - the strongest, but also hardest to use thing in [[Rust]]. [[I]] am just trying to rewrite my [[Sieve of Eratosthenes]] to [[Rust]] and it is almost impossible without reading [https://rust-unofficial.github.io/too-many-lists/ Too Many Lists] book. Will spending days of studying to implement something as trivial pay off?
