This is my experience every time I return to learning rust. I’m guessing that if I used it more often than once a quarter with hobby projects I’d stop falling into the same traps.

I find that the error messages themselves are a great tool for learning when it comes to Rust.

Eh, I’m not entirely sold on that idea.

I think they do a good job of pointing out “this is a behavior/feature of Rust you need to understand.” However they can send you down the wrong path of correction.

The compiler error mentioning static lifetime specifiers of &str demonstrates both. It indicates to the developer that ownership and scopes will play a significant role when defining and accessing data. The error though will guide them towards researching how to define static lifetimes and possibly believe that they will need to set this in their functions and structs. Each time you look at questions about this error in places like Stack Overflow with example code you’ll find suggested solutions explaining that a manually-defined static lifetime isn’t necessary to resolve the problem.
