    Summary: panic in user-provided `Endian` impl triggers double drop of T

    Details: Affected versions of the crate does not guard against panic from user-provided impl of `Endian` trait, which is a safe trait that users can implement. If a user-provided implementation of the `Endian` trait panics, double-drop is triggered due to the duplicated ownership of `T` created by `ptr::read()`. Double-drop (or double free) can cause memory corruption in the heap.
