That's one of Rust's selling points. For all I've used the rust compiler, not once have I ever not known what error it was pointing out: its error messages are incredibly helpful. Occasionally I am unsure why it's an error, but I always know what it's referring to and what I could do to fix it.

I've had the same experience with C#. The error messages always state exactly what's wrong and where in the code it's wrong. Many of them (especially compiler _warnings_ intended to point out syntax that is almost certainly a bug) also tell you how to fix it (e.g. “consider using ‘new’ keyword if hiding was intended”).

Personally, I don't know why the last one (“consider using ‘new’ keyword if hiding was intended”) isn't an error by default in C# . Not overriding the base method is almost always a mistake, and if it's not a mistake, better to be explicit about it, anyways. My $.02...
