Crate chio_store_sqlite 

SQLite-backed persistence, query, and report layer for the Chio protocol.

This crate is the concrete persistent backend for the kernel’s receipt log and its supporting state. It implements the receipt store and query path, budget and approval stores, capability-lineage and revocation stores, an execution-nonce store, an encrypted-blob store, IOU and dead-letter stores, and evidence-export queries. The store traits it implements are defined by chio-kernel and chio-core. Reader-heavy receipt queries use a connection pool (eight readers by default); writes are serialized through a group-commit actor onto a single writer connection.

Modules

• receipt_store / receipt_query – receipt persistence and the query path.
• budget_store – durable budget state.
• approval_store / batch_approval_store – human-approval state.
• capability_lineage / revocation_store – capability provenance and revocation.
• execution_nonce_store / dead_letters / iou_store – nonce replay guard, settlement dead letters, and IOU envelopes.
• encrypted_blob / memory_provenance_store / evidence_export – encrypted payloads, memory provenance, and evidence export.

Functions

is_in_memory_sqlite_path

Whether a SQLite path opens a database that lives only in memory for the life of the process. rusqlite enables URI filenames, so the bare :memory: sentinel, file::memory:, and any file:...?mode=memory URI all open a non-durable database that loses its contents on restart and must not be mistaken for a durable store. Durability gates use this to refuse an in-memory path where they would otherwise advertise durable persistence.

sqlite_filesystem_path

The filesystem path a rusqlite path points at, resolving a file: URI to its on-disk filename by stripping the scheme, any //authority, and the ?query. A plain path (no file: scheme) is returned unchanged.

Type Aliases

SharedCanonicalBytes
