Function core::hash::sip::load_u64_le

unsafe fn load_u64_le(buf: &[u8], i: usize) -> u64

Load a full u64 word from a byte stream, in LE order. Use copy_nonoverlapping to let the compiler generate the most efficient way to load u64 from a possibly unaligned address.

Unsafe because: unchecked indexing at i..i+8
