Summary by CodeRabbit

• Improvements

  • Improved consistency when handling JSON values across authorization, batch authorization, and data-store operations.
  • Enhanced batch authorization support with optional context handling and clearer malformed-input processing.
  • Archive loading now supports byte-buffer input for Android integrations.

• Compatibility

  • Updated language bindings to support the latest interface-generation tooling.
  • Improved interoperability for Java and Android applications using Cedarling.

📝 Walkthrough

Walkthrough

The UniFFI bindings now use a record-shaped JsonValue, UniFFI 0.32.0, and borrowed archive bytes. Rust, Java, Kotlin, and test code use the updated interfaces.

Changes

Cedarling UniFFI API migration

Layer / File(s)	Summary
Update UniFFI contracts and conversions jans-cedarling/bindings/cedarling_uniffi/Cargo.toml, jans-cedarling/bindings/cedarling_uniffi/src/lib.rs	UniFFI is upgraded to 0.32.0. JsonValue becomes a record with a value field. Optional batch context receives a default marker. Archive loading accepts byte slices and stores cloned bytes.
Adapt Java authorization and data-store calls jans-cedarling/bindings/cedarling-java/src/main/java/io/jans/cedarling/binding/wrapper/CedarlingAdapter.java	Authorization contexts, batch contexts, and data-store writes use JsonValue. Data-store reads extract and parse the underlying value.
Update binding and API tests jans-cedarling/bindings/cedarling_uniffi/src/tests.rs, jans-cedarling/bindings/cedarling-java/src/test/java/io/jans/cedarling/binding/wrapper/MultiIssuerBatchAuthzTest.java, jans-cedarling/bindings/cedarling-java/src/test/java/io/jans/cedarling/binding/wrapper/UnsignedBatchAuthzTest.java	Tests construct record-shaped JsonValue values, read the value field, pass archive bytes as slices, and update malformed batch contexts.
Update archive-byte examples jans-cedarling/bindings/cedarling_uniffi/androidApp/app/src/main/java/com/example/androidapp/MainActivity.kt, jans-cedarling/bindings/cedarling_uniffi/README.md	The Android example and its README convert policy archive bytes to direct, flipped ByteBuffer values before loading the archive.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: ⚪ Minimal · up to addc7

The UniFFI upgrade changes cross-language binding details while preserving existing validation and authorization behavior. Documentation for the default empty context remains a minor follow-up, but no actionable merge-blocking risk remains.

Full details: Description check

Explanation

The description includes the required preparation, target issue, testing checklist, and documentation-impact confirmation. The implementation details section is empty, but this is non-critical for this focused change.

Full details: Linked Issues check

Explanation

The PR upgrades UniFFI, adopts applicable default and byte-slice compatibility changes, updates Rust and Java-related tests, and updates the Android archive-loading example. The linked issue also requires developer documentation for version requirements and API or migration changes, but the PR explicitly states that documentation has no impact and the summarized README change does not document those requirements.

Resolution

Add developer documentation covering the UniFFI 0.32.0 requirement, the JsonValue record API change, the archive byte-slice API change, and any binding migration considerations. Also provide evidence that Rust and generated bindings build successfully after the upgrade.

Full details: Docstring Coverage

Explanation

Docstring coverage is 73.68% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff. Analyzed 19 functions across 3 files. (1 skipped: 1 unsupported.)

127-128: 📐 Maintainability & Code Quality | 🟡 Minor | ⚡ Quick win

Document the defaulted BatchItem.context field.

BatchItem.context is a public UniFFI field, and #[uniffi(default)] allows foreign callers to omit it. Add a field comment that states omitted context becomes an empty JSON object.

As per coding guidelines: “Document public API items.”

Proposed fix

 pub struct BatchItem {
     pub resource: Arc<EntityData>,
     pub action: String,
+    /// Optional JSON context. An omitted context uses an empty JSON object.
     #[uniffi(default)]
     pub context: Option<JsonValue>,
