Did you read the documentation for the fields pragma? It specifically mentions the differences between the pseudo-hash version for 5.8.x and lower, and the pseudo-hash free version for 5.9.x and higher. This distinction is made because, in 5.9.x and higher, pseudo-hashes will be gone. So, as long as you use fields;, and use fields::new, you should be safe, according to the documentation.
