If you haven't read the Rust Book at least, which is effectively Rust 101, you should not be writing Rust professionally. It has a chapter explaining all of this.

> In production-quality code, most Rustaceans choose expect rather than unwrap and give more context about why the operation is expected to always succeed. That way, if your assumptions are ever proven wrong, you have more information to use in debugging.

I didn't read anything in that section about unwrap/expect that it shouldn't be used in production code. If anything I read it as perfectly acceptable.
