Struct

Protocol for a NamedTuple representing structured binary data in a file.
namedtuple CR2WBufferInfo(flags, index, offset, disk_size, mem_size, crc32)[source]

Bases: NamedTuple

Metadata about a buffer in a CR2W/W2RC file.

Fields

  1.  flags (int) – Alias for field number 0

  2.  index (int) – Alias for field number 1

  3.  offset (int) – offset inside a cr2w file, buffers are compressed and appended to a cr2w file

  4.  disk_size (int) – This is the compressed size of the buffer; it’s called disksize because buffers are compressed and appended to a cr2w file

  5.  mem_size (int) – This is the uncompressed size of the buffer; it’s called memSize because buffers are uncompressed at runtime in the game

  6.  crc32 (int) – crc32 over the compressed buffer
