Module db 

Database handle and orchestration.

Database is implemented using internal modules open (bootstrap), replay (catalog and rows from segments), read / write / catalog_ops / maintenance (API surface), and helpers (name rules).

Structs

Collection

Database

Opened ModelVault database: generic over a Store (FileStore on disk, VecStore in memory).

DatabaseFileScan

Result of a read-only file scan (header, superblock, segments, decoded catalog).

QueryBuilder

SharedDbState

Live in-memory snapshot mirrored by the writable handle.

Enums

DatabaseScanMode

Controls whether segment framing / catalog decode runs during scan_database_file.

Constants

SEGMENT_REGION_START

Byte offset where the append-only segment region begins (after header + dual superblocks).

Functions

read_header_and_superblocks

Read and decode the fixed file header plus both redundant superblock slots.

rebuild_indexes_from_latest

Rebuild in-memory index state from catalog + latest rows (insert semantics only).

row_subset_by_field_defs

Build a row map containing only the listed fields (same rules as subset-model projection).

scan_database_file

Open path read-only and scan header, superblocks, and (when applicable) segments.

scan_database_store

Scan an already-open read-only FileStore.

select_superblock

Pick the newer valid superblock from the dual redundant slots.

verify_indexes_match_rows

Verify replayed index segments match what row data implies.
