New absolute finalized counts. Count 0 means the entry should be removed.
New absolute pending counts. Count 0 means the entry should be removed.
Deltas consumed by finalization or fork pruning.
Values that are no longer referenced and can be removed from the values DB.
Deltas of freshly imported blocks to persist.
A batch of refcounting mutations produced by a single
ValueRefsoperation.The backend is responsible for applying the batch using its own write primitive - ideally atomically with the state write that triggered it (one LMDB transaction, one fjall persist).
Counts are absolute values rather than increments, so applying the same update more than once (e.g. on crash-replay) is harmless.
When atomicity is not available, apply in field order and
removeValuesstrictly last: a crash after counts are persisted but before values are removed only leaks values, while the opposite order could drop a value the persisted counts still consider referencd.
