Module snapshot 

Portable validation and ordering for atomic operator snapshot restoration.

Structs

DatabaseSnapshot

A backend-independent operator artifact tied to its logical migration contract.

RestoreCount

An optional precondition checked against the transaction’s current snapshot.

Constants

OPERATOR_LIMITS

Default operator bounds keep bulk work outside request-sized transactions.

Functions

identity_filter 🔒

Resolves a complete primary identity without accepting undeclared fields.

restore_plan

A restore plan may execute only in the transaction that read its current records. It preserves numeric identities and checks references before any write.

validate_restore_records

Rejects malformed or oversized restore input before an adapter clones it or opens storage.

validated_order 🔒

Validates bounded records, uniqueness, and references in O((rows + links) log rows). Nullable links can cycle; non-null dependencies must admit an insertion order.

value_key 🔒

Normalizes exact decimal and timestamp keys before matching logical references.
