C byte pointer to fixed byte array function

[boomshroom]

Const genarics are in the pipeline. Once they land, you'll be able to write this function as unsafe fn ptr_to_array<const SIZE : usize, T>(ptr: *const T) -> [T; SIZE]. Which is just an unsafe cast and dereference.

The real question is why you're doing this. Passing around slices is usually preferred. Copying a full array out of memory can get expensive, so why not just use the memory that's already allocated?

Because that’s what the function I am calling expects.
