cmlabs::SlotEntryStruct Struct Reference

Per-message slot record: which bin/blocks hold the message and until when. More...

#include <TemporalMemory.h>

Public Attributes
uint16	serial
	Reuse serial; incremented when the slot is recycled and checked against the serial packed in the message id (wraps around).
uint64	eol
	Absolute end-of-life timestamp (µs); slot reclaimable after this.
uint32	bin
	Index of the bin holding the message data.
uint64	offset
	Byte offset of the message inside the bin's data area.
uint64	size
	Message byte size; 0 means the slot is not in use.
uint64	usage
	Bytes actually reserved (blocks used * blocksize >= size).
uint32	startBlock
	First block index used within the bin.
uint32	blockUsage
	Number of contiguous blocks used.

Detailed Description

Per-message slot record: which bin/blocks hold the message and until when.
