202-206: Verify deletion logic in OnDone.

The reactor deletes itself in OnDone. Ensure that this is safe and that no further operations are attempted on the reactor after deletion.

---

148-151: Verify deletion logic in OnDone.

The reactor deletes itself in OnDone. Ensure that this is safe and that no further operations are attempted on the reactor after deletion.

---

153-158: Verify deletion logic in OnCancel.

The reactor deletes itself in OnCancel. Ensure that this is safe and that no further operations are attempted on the reactor after deletion.

---

135-140: Ensure proper handling of write completion in OnWriteDone.

The method finishes with grpc::Status::OK if the write is not successful. Verify that this is the intended behavior and that it aligns with the overall logic.

Verification successful

Write Completion Handling in OnWriteDone is Consistent

The OnWriteDone method's behavior of finishing with grpc::Status::OK when a write is unsuccessful aligns with the class's overall strategy for handling operations. This approach is consistent with other methods like OnReadDone and OnCancel, ensuring a stable state by gracefully handling errors. No changes are necessary.

35-99: Implementation Review: server_bidi_reactor.

The server_bidi_reactor class is well-structured, utilizing base classes for handling read and write operations. Ensure that the error handling in OnReadDone, OnWriteDone, OnDone, and OnCancel is robust and that resources are properly managed with delete this.

---

112-167: Implementation Review: server_write_reactor.

The server_write_reactor class correctly implements the write-only server reactor pattern. Verify that the handling of OnWriteDone and OnCancel ensures proper completion and error signaling.

---

179-221: Implementation Review: server_read_reactor.

The server_read_reactor class implements the read-only server reactor pattern. Ensure that the OnReadDone and OnCancel methods handle stream completion and errors appropriately.

src/rpp/rpp/operators/subscribe.hpp (1)

327-331: Ensure the correctness of the new subscribe function.

The new subscribe function provides a streamlined way to handle only the completion of an observable. It uses default empty functions for OnNext and a rethrow error handler for OnError, which is appropriate for the intended use case. Ensure that this function is covered by tests to verify its behavior in different scenarios.

src/rpp/rpp/observables/observable.hpp (1)

208-212: Verify the functionality of the new subscribe overload.

The new overload for the subscribe method allows handling only the completion event. It uses default empty functions for OnNext and a rethrow error handler for OnError, which aligns with the intended use case. Ensure that this behavior is tested to confirm its functionality.
