pub type Opstamp = u64;
Expand description
A u64 assigned to every operation incrementally
All operations modifying the index receives an monotonic Opstamp. The resulting state of the index is consistent with the opstamp ordering.
For instance, a commit with opstamp 32_423
will reflect all Add and Delete operations
with an opstamp <= 32_423
. A delete operation with opstamp n will no affect a document added
with opstamp n+1
.
