13-15: Enhance concept documentationThe current documentation for the
IrUnitHandlerInterfaceconcept is quite brief. Consider expanding it to provide more context and usage information.Here's a suggested improvement:
/** * Concept that defines the IR unit handler interface. * * This concept specifies the required methods for handling various types of * Intermediate Representation (IR) units during deserialization. Any class * implementing this interface must provide implementations for handling * log events, UTC offset changes, schema tree node insertions, and * end-of-stream indicators. */
16-59: Concept definition looks good, minor suggestion for consistencyThe concept definition is well-structured and uses C++20 features appropriately. The method signatures and their documentation are clear and consistent.
For consistency, consider using
std::forwardfor theschema_tree_node_locatorparameter inhandle_schema_tree_node_insertion, similar to how it's used forlog_eventinhandle_log_event. This would allow for more flexible usage of the interface. Here's the suggested change:{ - handler.handle_schema_tree_node_insertion(schema_tree_node_locator) + handler.handle_schema_tree_node_insertion(std::forward<SchemaTree::NodeLocator>(schema_tree_node_locator)) } -> std::same_as<IRErrorCode>;components/core/tests/test-ffi_IrUnitHandlerInterface.cpp (3)
26-80: LGTM: TrivialIrUnitHandler class is well-implemented.The class correctly implements the IrUnitHandlerInterface and provides appropriate methods for testing. The use of [[nodiscard]] is good practice.
Consider adding brief comments for each method to explain their purpose and any side effects.
82-114: LGTM: test_ir_unit_handler_interface function provides good coverage.The function effectively tests all required methods of the IrUnitHandlerInterface. The use of REQUIRE statements ensures proper error checking.
Consider adding more specific assertions to verify the expected state changes after each operation, in addition to checking for success codes.
117-140: LGTM: Template test case provides comprehensive coverage.The test case effectively uses TEMPLATE_TEST_CASE to test both handler types. It covers initial state, interface operations, and final state verification comprehensively.
Consider adding a test case with invalid input to ensure the handler behaves correctly under error conditions.

60-62: Proper closure of namespace and header guardThe namespace is correctly closed, and the header guard is properly terminated. This follows good C++ practices.
1-62: Well-implemented interface aligning with PR objectivesThis new header file successfully introduces the
IrUnitHandlerInterfaceconcept, aligning well with the PR objectives. The use of C++20 concepts instead of traditional inheritance eliminates virtual call overhead, as intended. The interface is well-defined, properly documented, and provides the necessary flexibility for user-defined handling of various IR unit types.The implementation is consistent with the PR summary and demonstrates good C++ coding practices. It lays a solid foundation for the functionality described in issue #539.
components/core/tests/test-ffi_IrUnitHandlerInterface.cpp (3)
1-19: LGTM: Includes and using declarations are appropriate.The necessary headers are included, and the using declarations improve code readability by simplifying type names.
21-24: LGTM: Constants are well-defined and appropriately used.The constants are properly named, typed, and use constexpr for potential compile-time optimizations.
1-140: Overall, excellent implementation of unit tests for IrUnitHandlerInterface.The file provides comprehensive test coverage for the IrUnitHandlerInterface, including all required methods and state verification. The use of templates allows testing multiple handler types efficiently.
Minor suggestions for improvement:
- Add brief comments to methods in the TrivialIrUnitHandler class.
- Include more specific state change assertions in the test_ir_unit_handler_interface function.
- Consider adding test cases for error conditions.
These enhancements would further improve the already solid test implementation.

Description
This PR adds
IrUnitHandlerInterfaceas described in #539. These methods will be called inside the IR stream deserializer to perform user-defined handling for each type of IR unit.Regarding design choice, we will use
conceptto define methods required from a user-implemented handler. OOP with inheritance is not used to avoid the virtual call overhead.We also add a unit test with a trivial handler that doesn't do anything meaningful to test the interface's basic functionality and show an example of implementing a handler. The unit test also ensures the concept template can be properly compiled with a correct interface implementation.
