Binary serialization for Tensor with primitive Double, Float, Long

The layout of binary format is as follows: - The first 6 bytes are "LAMP" - The next unsigned byte is the major version - The next unsigned byte is the minor version - The next 4 bytes form a little endian integer as HEADER_LENGTH - The next HEADER_LENGTH bytes form an UTF-8 string as the header. - The header is a valid JSON object with the following fields:

  • v: numeric positive integer is the version of the header structure
  • shape: numeric array
  • datatype : string, either "double", "long", "int", "float", "byte" - The header is padded with spaces (0x20) such that HEADER_LENGTH+12 is divisible by 16. The count of spaces are included in HEADER_LENGTH. - The next width * shape.reduce(_ * _) bytes form a little endian primitive array.
