It's now been about five years since I heard about the Rust programming language for the first time. It was when I was starting to write an operating system in C and the "Rust people" (as they seem to often refer to themselves, which should already be a red flag) told me that I should write it in Rust. (Later, they have several times told me to rewrite it in Rust.) Rust is "memory safe", which in the context of Rust means that the whole language is designed in such way that it is impossible to have memory-related bugs in programs that are written in Rust.
