DESCRIPTION

       Sereal is an efficient, compact-output, binary and feature-rich serialization protocol. The Perl encoder
       is implemented as the Sereal::Encoder module, the Perl decoder correspondingly as Sereal::Decoder. They
       are distributed separately to allow for safe upgrading without downtime. (Hint: Upgrade the decoder
       everywhere first, then the encoder.)

       This "Sereal" module is a very thin wrapper around both "Sereal::Encoder" and "Sereal::Decoder". It
       depends on both and loads both. So if you have a user of both encoder and decoder, it is enough to depend
       on a particular version of "Sereal" and you'll get the most recent released versions of "Sereal::Encoder"
       and "Sereal::Decoder" whose version is smaller than or equal to the version of "Sereal" you depend on.

       The protocol specification and many other bits of documentation can be found in the github repository.
       Right now, the specification is at <https://github.com/Sereal/Sereal/blob/master/sereal_spec.pod>, there
       is a discussion of the design objectives in <https://github.com/Sereal/Sereal/blob/master/README.pod>,
       and the output of our benchmarks can be seen at
       <https://github.com/Sereal/Sereal/wiki/Sereal-Comparison-Graphs>.

   EXPORTED FUNCTIONS
       It is recommended to use the object-oriented interface of "Sereal::Encoder" and "Sereal::Decoder" if you
       care about performance. For detailed performance considerations, see Sereal::Performance.

       You can optionally import five functions from "Sereal".  "encode_sereal" is the same function as
       Sereal::Encoder's "encode_sereal" function. "decode_sereal" and "looks_like_sereal" are the same as
       Sereal::Decoder's functions of the same names.  Finally, you can import the advanced functional interface
       "sereal_encode_with_object" and "sereal_decode_with_object".  Again, see Sereal::Performance for
       information about those.

       After loading the "Sereal" module, both "Sereal::Encoder" and "Sereal::Decoder" are guaranteed to be
       loaded, so you can use their object-oriented interface.

   get_sereal_encoder($OPTSHASH)
       Returns a Sereal::Encoder with the given options. This encoder will be shared by other calls to this
       function.

   get_sereal_decoder($OPTSHASH)
       Returns a Sereal::Decoder with the given options. This encoder will be shared by other calls to this
       function.

   clear_sereal_object_cache
       Clears cache of objects created via get_sereal_encoder() and get_sereal_decoder(). Returns the number of
       objects that were removed from the cache (the sum of both types).

   write_sereal_file($FILENAME,$STRUCT,$APPEND,$OPTS)
       Write a sereal packet to $FILENAME. See Sereal::Encoder::encode_to_file().

   write_sereal($FILENAME,$STRUCT,$APPEND,$OPTS)
       alias for write_sereal_file()

   read_sereal_file($FILENAME,$OPTS,$ROOT)
       Read a sereal packet from a file. See Sereal::Decoder::decode_from_file().

   read_sereal($FILENAME,$OPTS,$ROOT)
       alias for read_sereal_file()
