The Rot13 typeclass is intended to perform the ROT13 cipher on the provided data, as if it were representing a single ANSI-encoded character. This interface doesn't consider the storage behaviour of the type at all, but is the fastest implementation if you need to integrate the transformation as part of a stream.

The Rot13Bytes typeclass is intended for when you need to perform the ROT13 cipher on some data at the memory level. It stores the given data into a temporary buffer in memory, then runs the cipher over the stored bytes to produce a new buffer. This operation is typically slower than just using rot13 as part of a fusion pipeline.

Perform the ROT13 cipher on the given Enum instance (in the sense of Rot13).

Perform the ROT13 cipher on the given Integral instance (in the sense of Rot13).
