Detailed Description

Representation of compressed data:

  • compressed data should have preallocated size via bitSize param in constructor. its preallocated size is defined in "size" property
  • current size of compressed data is stored in "cursor" property ( its value defines amount of used bits )
  • compressed data is not affected by memory alignment, and is stored in LIFO order
  • it should be mid layer used for serialization in the future
