It's kind of both. I experienced this with Advent of Code, the other day where I had a vague idea of the data structure I was trying to work with, and the approach I wanted to take to solve the problem, but I started banging into errors from the compiler. I had to step back and take a moment to think about exactly what I was trying to do and what that meant for the model I was using. My approach wasn't wrong and it likely would have worked on my first shot in Python or C# or something, but the fact that Rust cares about ownership meant I had to think about it too, even if I only really did that after the compiler pointed out that there were some issues.
