Struct VersionedReadSet 

pub struct VersionedReadSet(pub Vec<VersionedReadEntry>);

The LSN-versioned read-set of a Calvin transaction.

Empty for pure-write transactions and for autocommit statements (which accumulate no session read-set). Populated at commit time from the neutral session read-set, and validated per-participant against the local write-version index at Calvin stage time (the commit vote on read_set_valid).

Tuple Fields

0: Vec<VersionedReadEntry>
