Structs
The Guide structure is hydrated from its in-memory representation, 64 bits in length.
The top 32 bits contain the hash, the bottom 32 bits contain the collection’s count.
The highest order bit of the bottom 32 bits represent whether
the representation is compact (no info unit).
So a collection’s count resides in the 31 lowest order bits.
Top 32 bits [ Hash (32) ]
Bottom bits [ Compact? | Count (31) ]
