I wrote and deployed a production service written in pre-1.0 Rust. In over three years of being deployed I never once had to touch that code. The infrastructure around it evolved several times, we even moved cloud providers in that time, but that particular service didn't need any changes or maintenance. It just kept chugging along.
Perhaps Rust's name is apropos: your code will be so reliable that you won't need to look at it again until it has collected rust on its thick iron framework.
