Detailed Description

Structure of a single log entry in the log.

This can't be represented as a structure because the payload is of variable size, i.e.

Offset	Name
0	TIMESTAMP
8	IV_COUNTER
12	PARTITION ID
16	SIZE
20	RECORD ID
24	PAYLOAD
20+SIZE	MAC

SIZE: at least LOG_MIN_SIZE bytes, known only at runtime. It's the size of the (RECORD_ID, PAYLOAD) fields

MAC_SIZE: known at build time (currently, 4 bytes)

At runtime, when adding a record, the value of SIZE has to be checked and must be less than LOG_SIZE - MAC_SIZE - 12 and equal or greater than LOG_MIN_SIZE

The documentation for this struct was generated from the following file:
