A tiny utility crate for finding the offset of a subslice within another slice. Note that this is not done through pattern matching but with pointer arithmetic instead.
To use, simply include this crate and use the [SubsliceOffset] trait. The [subslice_offset][SubsliceOffset::subslice_offset] method should then appear on [slices][slice].
I do not take any credit for this crate, full credit goes to https://stackoverflow.com/a/50781657
