sekejap 0.19.4

Embedded graph-first multi-model database (SQL + graph + vector + spatial). dart:ffi bindings over the sekejap C ABI, for Dart and Flutter.

Changelog

0.17.0

The wrapper is now dart:ffi over the sekejap C ABI. It is a rewrite, not an upgrade: every call has a new spelling.

Changed

• The binding. flutter_rust_bridge over a Rust glue crate is gone; the package binds libsekejap (dist/ffi, contract docs/dist/C_ABI.md) directly with dart:ffi. All 59 C functions are exposed, one Dart call each.
• Pure Dart. The package no longer depends on Flutter and is no longer a Flutter plugin. It works unchanged in a Dart CLI, a server and a Flutter app. Its one dependency is package:ffi.
• A row is a collection and a key, not one slug string: db.put('dish', 'd1', {…}), db.get('dish', 'd1').
• Handles are classes. Db, Statement, Scan, Transaction, each freed by its own close() and all of them before the Db they borrow.
• Errors are exceptions. A failure throws SekejapException carrying both channels of the ABI: the closed SekejapStatus and the message sekejap_last_error wrote on this thread. A miss stays null.

Removed

• flutter_rust_bridge and the generated lib/src/rust/ bindings, and the rust/ glue crate (sekejap_ffi) they were generated from. The C ABI is the binding now, and the header is generated from dist/ffi/src/lib.rs.
• cargokit and the android/, ios/, linux/, macos/, windows/ plugin folders. They existed to build the glue crate from source on a consumer's machine; there is no glue crate to build. Ship the platform's libsekejap with the app instead — see the README.
• dbNew (an in-memory database). sekejap is disk-first and has no in-memory store; Db.openMemory() keeps the name and refuses with the reason.
• The typed model layer — @SekejapEntity, Collection, Query, Filter, Sekejap.open(schema:) — and the sekejap_generator package that generated it. It was a second front end over the old Rust glue's API and does not describe the 0.17 surface. The wrapper mirrors the C functions one to one; a typed layer over these calls is separate work.
• dbSetWalSync and the mobile profile call. Store configuration is set at open, once: Db.openWithConfig(path, StoreConfig(sync: SyncMode.normal)).
• watchChanges. The change feed has a service behind it now: Db.openService, subscribe, nextChange, unsubscribe.

Added

• Service mode: Db.openService, subscribe/nextChange/unsubscribe, statementTimeoutMs, cancel, clearInterrupt.
• Transactions: db.transaction() with put, delete, link, execute, commit, rollback.
• Paged walks: db.scan(collection) and db.stream(sql, params, pageRows).
• The catalog: createCollection, dropCollection, collections, describe, countRows, scanCountRows, scanCountEdges.
• checkpoint, publish, storage, explain.
