# I'd have liked to do the byte&0xF0 matching against 0, 1, 2 ... by
|
||
|
|
# doing (byte&0xF0)>>4 here, but unfortunately that's not
|
||
|
|
# supported. So when we print out a message about an unknown format
|
||
|
|
# we'll print out e.g. 0x30 instead of the more human-readable
|
||
|
|
# 0x30>>4.

# See https://github.com/Sereal/Sereal/commit/35372ae01d in the
|

|
|
# Sereal.git repository for test Sereal data.
