## [2026-08-20] - ADL-005: chronogrid_ffi Crate – Flutter Rust Bridge v2 FFI Layer
|
||||||
|
|
||||||
|
- **Status**: Accepted
|
||||||
|
- **Context**: Task 1.5 required generating `flutter_rust_bridge` FFI bindings to bridge all Rust storage, CRDT, and cryptographic methods to the Flutter/Dart presentation layer.
|
||||||
|
- **Decision**:
|
||||||
|
- Created `crates/chronogrid_ffi/` crate with `cdylib` + `staticlib` + `lib` targets, depending on `chronogrid_core`, `chronogrid_crypto`, `flutter_rust_bridge = "=2.7.0"`, and `anyhow = "1"`.
|
||||||
|
- API uses a **serialized-bytes pattern**: CRDT documents cross FFI as `Vec<u8>` (Automerge binary); read functions return DTO structs (`FfiTaskData`, `FfiNoteData`, `FfiDerivedKey`).
|
||||||
|
- Global `Engine` singleton (`Mutex<Option<Engine>>`) holds the `Database` connection + `Hlc` clock. Thread-safe `with_engine()` / `with_engine_mut()` helpers provide access from FRB's isolate thread pool.
|
||||||
|
- 38 public FFI functions across 5 API modules: `engine` (init/close/status), `database` (CRDT doc persistence), `crypto` (key derivation + platform-gated keychain), `task_crdt` (18 create/read/set/clear/merge ops), `note_crdt` (8 create/read/set/clear/merge ops).
|
||||||
|
- All fallible functions return `anyhow::Result<T>`, which FRB v2 maps to Dart exceptions.
|
||||||
|
- Keychain functions compile on all platforms but return an error on Android (delegated to Flutter KeyStore bridge).
|
||||||
|
- `flutter_rust_bridge.yaml` configures codegen: Rust input from `api/`, Dart output to `apps/chronogrid_flutter/lib/src/rust/`.
|
||||||
|
- Flutter `pubspec.yaml` updated with `flutter_rust_bridge: ^2.7.0`, `ffi: ^2.1.0`, `meta: ^1.11.0`.
|
||||||
|
- 25 unit tests (all passing): engine lifecycle, DB CRDT doc persistence, task/note CRDT create/read/mutate/merge round-trips, crypto derivation, stateless read validation, no-engine error paths.
|
||||||
|
- Full ADR at `docs/ARCHITECTURE/ADR/0005-ffi-bridge-flutter-rust-bridge.md`.

//!

//! After modifying the `api/` module, run:

//! ```bash

//! flutter_rust_bridge_codegen generate
|

//! ```

//!

//! This produces `src/frb_generated.rs` (Rust glue) and Dart binding files in

//! the Flutter project. The generated Rust module is included below only when

//! the file exists (i.e., after the first codegen run).

# ADR-0005: FFI Bridge via Flutter Rust Bridge v2
|
||||||
|
|
||||||
|
- **Status**: Accepted
|
||||||
|
- **Date**: 2026-08-20
|
||||||
|
- **Task**: 1.5 — Generate flutter_rust_bridge FFI bindings bridging Rust storage methods to Dart
|
||||||
|
|
||||||
|
## Context
|
||||||
|
|
||||||
|
Tasks 1.1–1.4 established the Rust core engine (`chronogrid_core` with SQLCipher + Automerge CRDT) and the cryptographic primitives (`chronogrid_crypto` with Argon2id KDF + OS keychain). The Flutter presentation layer needs a type-safe, zero-copy FFI bridge to invoke these Rust functions from Dart.
|
||||||
|
|
||||||
|
The project's architectural mandate (`.clinerules`) requires: *"FFI Bridge: Use `flutter_rust_bridge` C-ABI generation ONLY."*
|
||||||
|
|
||||||
|
## Decision
|
||||||
|
|
||||||
|
### 1. New Crate: `chronogrid_ffi`
|
||||||
|
|
||||||
|
A dedicated bridge crate (`crates/chronogrid_ffi/`) was created with:
|
||||||
|
|
||||||
|
- **`[lib] crate-type = ["lib", "cdylib", "staticlib"]`** — produces a shared library for Flutter's FFI loader on all platforms, plus a static library for iOS.
|
||||||
|
- **Dependencies**: `chronogrid_core`, `chronogrid_crypto`, `flutter_rust_bridge = "=2.7.0"`, `anyhow = "1"`.
|
||||||
|
|
||||||
|
### 2. API Surface Design — Serialized CRDT Bytes + Engine Singleton
|
||||||
|
|
||||||
|
Rather than passing opaque Rust pointers across FFI, the API uses a **serialized-bytes pattern**:
|
||||||
|
|
||||||
|
- **CRDT documents** are serialized to/from `Vec<u8>` (Automerge binary format).
|
||||||
|
- **Mutation functions** accept `doc_bytes: Vec<u8>`, apply the edit, and return updated `Vec<u8>`.
|
||||||
|
- **Read functions** (`task_crdt_read`, `note_crdt_read`) deserialize bytes into FFI-safe DTO structs (`FfiTaskData`, `FfiNoteData`).
|
||||||
|
- **Merge functions** are stateless — they accept two document byte arrays and return the merged result.
|
||||||
|
|
||||||
|
This avoids opaque pointer lifetime management, ensures Dart never holds stale Rust references, and leverages Automerge's natural serialization boundary.
|
||||||
|
|
||||||
|
### 3. Engine Singleton (`Mutex<Option<Engine>>`)
|
||||||
|
|
||||||
|
A global `Engine` struct holds:
|
||||||
|
- `db: Database` — the open SQLCipher connection.
|
||||||
|
- `hlc: Hlc` — the node's Hybrid Logical Clock.
|
||||||
|
|
||||||
|
The engine is stored in a `static Mutex<Option<Engine>>` with helper functions `with_engine()` and `with_engine_mut()` for safe concurrent access from FRB's thread pool.
|
||||||
|
|
||||||
|
- `init_engine(path, key, node_id)` / `init_engine_in_memory(key, node_id)` — opens the database and seeds the HLC.
|
||||||
|
- `close_engine()` — drops the connection.
|
||||||
|
- `is_engine_initialized()` — status check.
|
||||||
|
|
||||||
|
### 4. Module Structure
|
||||||
|
|
||||||
|
| Module | Functions | Category |
|
||||||
|
|----------------|-----------|----------|
|
||||||
|
| `engine` | 4 | Lifecycle (init/close/status) |
|
||||||
|
| `database` | 3 | CRDT doc persistence (save/load/delete) |
|
||||||
|
| `crypto` | 5 | Key derivation + keychain (platform-gated) |
|
||||||
|
| `task_crdt` | 18 | Task CRDT create/read/set_*/clear_*/merge |
|
||||||
|
| `note_crdt` | 8 | Note CRDT create/read/set_*/clear_*/merge |
|
||||||
|
| `types` | 3 structs | `FfiDerivedKey`, `FfiTaskData`, `FfiNoteData` |
|
||||||
|
|
||||||
|
**Total**: 38 public FFI functions + 3 DTO structs.
|
||||||
|
|
||||||
|
### 5. Error Handling
|
||||||
|
|
||||||
|
All fallible functions return `anyhow::Result<T>`, which FRB v2 automatically maps to Dart exceptions with the error message string. Internal `CoreError` and `CryptoError` variants are converted via their `Display` impls.
|
||||||
|
|
||||||
|
### 6. Platform Gating
|
||||||
|
|
||||||
|
Keychain functions (`crypto_store_credential`, `crypto_retrieve_credential`, `crypto_delete_credential`) compile on all platforms but return an error on Android, where credential storage is delegated to the Flutter KeyStore bridge.
|
||||||
|
|
||||||
|
### 7. Code Generation Config
|
||||||
|
|
||||||
|
`flutter_rust_bridge.yaml` at workspace root configures the codegen:
|
||||||
|
- **Rust input**: `crates/chronogrid_ffi/src/api/`
|
||||||
|
- **Rust output**: `crates/chronogrid_ffi/src/frb_generated.rs`
|
||||||
|
- **Dart output**: `apps/chronogrid_flutter/lib/src/rust/`
|
||||||
|
|
||||||
|
After running `flutter_rust_bridge_codegen generate`, the `frb_generated` module must be uncommented in `lib.rs`.
|
||||||
|
|
||||||
|
### 8. Flutter Side
|
||||||
|
|
||||||
|
`pubspec.yaml` updated with `flutter_rust_bridge: ^2.7.0`, `ffi: ^2.1.0`, and `meta: ^1.11.0`.
|
||||||
|
|
||||||
|
## Testing
|
||||||
|
|
||||||
|
- **25 unit tests** covering: engine lifecycle (init/close/double-init/bad-key), database CRDT doc persistence (save/load/delete/missing), task CRDT (create/read/set-all-fields/clear-optionals/merge/stateless-read/no-engine-error), note CRDT (create/read/set-all-fields/clear-optionals/merge/stateless-read/no-engine-error), and crypto (derive/deterministic/invalid-salt/generate-salt).
|
||||||
|
- All 25 tests pass with `--test-threads=1` (required due to global engine singleton).
|
||||||
|
- Verification pipeline (`scripts/verify_agent_work.ps1`) passes all checks.
|
||||||
|
|
||||||
|
## Consequences
|
||||||
|
|
||||||
|
- The Dart presentation layer can invoke all core Rust functionality via generated type-safe bindings after a single `flutter_rust_bridge_codegen generate` run.
|
||||||
|
- CRDT documents flow as opaque byte arrays across FFI, maintaining the local-first zero-cloud mandate.
|
||||||
|
- The engine singleton pattern means only one database can be open at a time per process, which matches the single-user design.
|
||||||
|
- Future phases can extend the API by adding new `pub fn` entries to the `api/` modules and re-running codegen.
