View Source PropertyTable.PersistFile (property_table v0.2.3)
This module contains methods to aid in writing the contents of a PropertyTable to a custom file format.
The structure of the format is the following:
+------------------------------+
| HEADER 'PTABLE' | Used to initially validate the file [0x00]
+------------------------------+
| FILE VERSION (uint8) | Used to track the internal PropertyTable structure of the file [0x06]
+------------------------------+
| RESERVED (8 bits) | Reserved [0x07]
+------------------------------+
| PAYLOAD SIZE (uint64) | Length in bytes of the payload that follows [0x08]
+------------------------------+
| PAYLOAD BYTES (above size) | Raw erlang term bytes of the table contents [0x10]
+------------------------------+
| PAYLOAD HASH (MD5 128 bits) | MD5 Checksum of the bytes when they were written, ensures table integrity [0x10 + payload_size]
