It’s the same as using “unsafe” in rust, it shouldn’t be necessary by default, but when you do need it, you can have a well-defined part that safely encapsulates all the logic of dealing manually with memory. The end result will be a safe program with the assumed memory/performance-bottleneck of doing it naively solved.
