8-8: LGTM! Documentation accurately reflects the architectural changes.
The updated documentation clearly explains the new design using ReaderInterface, and the new include statement is properly placed.
Also applies to: 13-15
23-24: LGTM! Constructor properly implements the new design.
The constructor correctly handles ownership transfer of the reader and deserializer using move semantics.
Also applies to: 27-27
42-45: LGTM! Well-designed getter method.
The method is properly marked with [[nodiscard]] and returns a reference, which is appropriate for this use case.
50-50: LGTM! Getter properly updated for new template parameter.
The return type correctly reflects the template parameter change while maintaining reference semantics.
54-55: LGTM! Member variables properly reflect the new design.
The member variables are correctly updated to match the new template-based approach. Let's verify the usage of this updated class throughout the codebase.
✅ Verification successful
Member variables are correctly used with the new template-based design
The verification confirms that StreamReaderDataContext is consistently used with the UnstructuredIrDeserializer template parameter throughout the codebase. All instances properly handle the templated type and maintain the updated member variables (m_reader and m_deserializer).

10-10: Well-structured type alias introduction!
The addition of the LogEventDeserializer include and the UnstructuredIrDeserializer type alias improves code maintainability while properly setting up the template specialization.
Also applies to: 21-21
85-86: Clean member variable update!
The member variable type has been properly updated to use UnstructuredIrDeserializer while maintaining the unique_ptr ownership semantics. The line split improves readability.
80-82: Verify create() method implementation
The constructor signature has been properly updated to use UnstructuredIrDeserializer. However, the create() method still shows ZstdDecompressor in its signature. Let's verify its implementation.
✅ Verification successful
Create() method implementation is consistent with constructor changes
The create() method implementation correctly uses UnstructuredIrDeserializer internally while maintaining its existing interface. This is the expected pattern since:
- The method accepts a ZstdDecompressor which is passed to UnstructuredIrDeserializer::create()
- The constructor signature change aligns with this implementation as it receives the constructed UnstructuredIrDeserializer
- This maintains proper encapsulation of the UnstructuredIrDeserializer creation details

8-8: Documentation accurately reflects the architectural changes
The updated documentation and include statement properly reflect the shift to using a generic ReaderInterface and deserializer type, which aligns well with the PR's objective of making the class more flexible.
Also applies to: 13-15
17-17: Template parameter change enhances flexibility
The change from encoded_variable_t to deserializer_t better represents the parameter's purpose and enables the class to work with different deserializer types, which is essential for supporting both structured and unstructured IR stream readers.
45-45: Method signature properly updated
The get_deserializer method correctly reflects the template parameter change while maintaining const-correctness and the nodiscard attribute.
49-50: Member variables properly reflect new design
The member variables are well-named and their types correctly correspond to the constructor parameters, maintaining a clean and consistent design.
23-24: Constructor changes promote better abstraction
The switch to ReaderInterface improves flexibility while maintaining efficient resource management through move semantics.
Let's verify that all implementations of ReaderInterface are properly handled:
Also applies to: 27-27
✅ Verification successful
Constructor changes are correctly implemented and safe
The verification confirms that ReaderInterface is properly used throughout the codebase:
- It's correctly included and used in
StreamReaderDataContext.hpp - The interface is consistently used in related components (
StreamReader.cpp) - The ownership transfer is properly handled through
std::unique_ptr - The implementation maintains compatibility with the existing reader hierarchy (
StreamReader,UnstructuredIrStreamReader)

219-224: LGTM! Constructor changes are well-implemented.
The changes to the constructor signature and member initialization correctly implement the template parameter update while maintaining proper move semantics.
Line range hint 42-224: Please verify the impact of these changes.
While the changes look good, please ensure:
- All callers of
UnstructuredIrStreamReader::createhave been updated to handle any potential changes in error conditions - The switch to template-based deserializer type doesn't introduce any performance overhead
✅ Verification successful
Let me check the actual implementation of the callers to better understand the impact.
Let me check one more aspect to verify the error handling pattern and performance implications.
Changes are safe and properly handled
Based on the code analysis:
- The only caller in
StreamReader.cppproperly handles the creation and error cases through the existing error propagation mechanism - The template-based changes follow the established patterns in the codebase and don't introduce additional runtime overhead as they are resolved at compile time
- No performance-critical code paths are affected

This should be Deserializer since it's a non-primitive. We only use snake_case_t for primitive type defs.
