Rust's errors are definitely the best of any language I've used. That's one reason it's nice to write Rust after a day fighting with SQL Server for example which seems to still think in 2021 that "Syntax error" is a reasonable diagnostic message.
As to "How to fix it" however if you have lifetime confusion the error reported by the borrow checker probably isn't going to suggest refactoring your code with a design that makes sense even though that's likely the correct solution. It would be cute if the Rust compiler said "I think you want a Boxed collection of strings here to use the algorithm you're attempting, change how this is represented in all the related structs too, here's how:" but that's unrealistic and, more importantly, no other language is doing a better job here.
While Rust makes the errors themselves look easy, the right suggestion is context sensitive anyway. In my AoC solutions, unwrap() was the correct answer anywhere the problem is "I have an Option or a Result and I wish that I didn't". Because it's AoC if I'm wrong to be so cavalier I will eat a panic immediately, and I don't plan to maintain this stuff. In a real project I probably want to explicitly handle None and Error in some places, and pass on Errors in other places, even when I don't I should write an expect() in case I'm maintaining this years from now.
More likely in lifetime confusion scenarios the equivalent C++ compiles but just has mysterious crashes or bugs and the equivalent Java has runtime Null reference errors, Concurrency errors, a truly enormous memory leak, data races, other mysterious mutation bugs, or all of the above. I'll take a compile time error from the borrow checker thanks.
