storeRebuildParseEntry()

bool storeRebuildParseEntry	(	MemBuf &	buf,
		StoreEntry &	e,
		cache_key *	key,
		StoreRebuildData &	counts,
		uint64_t	expectedSize
	)

Parses the given Store entry metadata, filling e and key. Optimization: Both e and key parameters may be updated even on failures.

Parameters

buf	memory containing serialized Store entry swap metadata (at least)
e	caller's temporary StoreEntry object for returning parsed metadata
key	caller's temporary Store entry key buffer; usable to set e.key
expectedSize	either total entry size (including swap metadata) or 0

Return values

true	success; e/key filled with parsed metadata
false	failure; e/key ought to be ignored (may be filled/dirty)
