prettyHexEnc :: Encoding -> String

Pretty prints an Encoding in an annotated, hexadecimal format that maps CBOR values to their types. The output format is similar to the format used on http://cbor.me/.

For example, with the term:

putStrLn . prettyHexEnc . encode $
  ( True
  , [1,2,3::Int]
  , (fromList [("Hello",True),("World",False)], "This is a long string which wraps")
  )

You get:

83      # list(3)
   f5   # bool(true)
   9f   # list(*)
      01        # int(1)
      02        # int(2)
      03        # int(3)
   ff   # break
   82   # list(2)
      a2        # map(2)
         65 48 65 6c 6c 6f      # text("Hello")
         f5     # bool(true)
         65 57 6f 72 6c 64      # text("World")
         f4     # bool(false)
      78 21 54 68 69 73 20 69 73 20 61 20 6c 6f 6e 67
      20 73 74 72 69 6e 67 20 77 68 69 63 68 20 77 72
      61 70 73          # text("This is a long string which wraps")
