WebbTBH I don't think it is worth changing your current code. In this case all the array lengths are known at compile time so I would be surprised if the compiler didn't take an advantage of this and inline calls to copy_from_slide and thus get rid of all the panicing branches. I believe these are the most basic optimizations compilers do these days.
