Module checksummed 

Checksum-trailer framing.

Checksummed wraps any Framer and appends a fixed-size checksum after each inner frame:

+----------------------------+----------------+
| inner frame (header,       | checksum       |
| payload, delimiter, ...)   | (C::LEN bytes) |
+----------------------------+----------------+

The trailer sits outside the inner frame, so the inner framer is used unchanged and nothing has to be copied or buffered on either path. For a length-prefixed inner framer the prefix counts the payload only, which is the layout of many serial and embedded protocols.
