decode(%param)

Resolve the given writer and reader_schema to decode the data provided by the reader.

• writer_schema

  The schema that was used to encode the data provided by the "reader"

• reader_schema

  The schema we want to use to decode the data.

• reader

  A file handle, or an object implementing a similar interface, like IO::File. Specifically, it must support "read($buf, $nbytes)" and "seek($nbytes, $whence)". These calls will block the decoder if not enough data is available for read.
