117-121: Update the documentation to reflect the new return type.The documentation for the
querymethod still mentionsFalkorResultSetwhich seems to be a leftover from the previous implementation. Please update it toLazyResultSetto match the new method signature.
137-137: Ensure consistency in documentation.The documentation for the
ro_querymethod does not specify the return type in the description. It would be beneficial for clarity to include that it returns aQueryBuilderobject configured for a read-only query that will yield aQueryResult<LazyResultSet>.

18-44: TheStatisticTypeenum is well-defined with clear serialization values for each statistic type. This will facilitate easy parsing and usage in logging or reporting features.
48-48: TheQueryResultstruct is well-structured to encapsulate the header, data, and statistics of a query response. This struct will centralize response handling and improve the maintainability of the code.

197-198: Consider refactoring to reduce redundancy in index-related methods.This comment is a continuation of the previous suggestion to refactor repeated code patterns in index-related methods. Consider creating a private helper method to construct these query strings to reduce redundancy and improve maintainability.
309-310: Validate the integration ofQueryResultin constraint-related methods.The update to return
QueryResultinlist_constraintsmethod is in line with the PR's goals of enhancing API consistency and handling query results more effectively.
275-275: Verify the correct handling of index types in thedrop_indexmethod.Verification successful
The
ast-grepsearch results indicate that there is a match statement handling different index types withinsrc/graph/blocking.rs. Specifically, it handlesIndexType::Range,IndexType::Vector, andIndexType::Fulltext. We need to verify that this match statement is part of thedrop_indexmethod and that the method uses it correctly.To ensure the match statement is within the
drop_indexmethod and verify the method's handling of index types, we need to gather the relevant method implementation.
The previous script did not produce any output, indicating that it did not find the
drop_indexmethod with the provided pattern. To adjust our approach, we will search for the method name itself and then inspect its implementation.
The
drop_indexmethod has been located, and part of its implementation has been extracted. The method includes a match statement handling different index types. To ensure the correct handling of index types, we need to review the complete implementation of the method.
The complete implementation of the
drop_indexmethod has been extracted. The method includes a match statement that handles different index types (IndexType::Range,IndexType::Vector, andIndexType::Fulltext) and constructs the appropriate query string for dropping the index.
- The match statement correctly maps each
IndexTypeto its corresponding string representation.- The constructed query string uses this mapping to drop the index for the specified entity type and properties.
This confirms that the
drop_indexmethod correctly handles the different index types.Scripts executed

The get_statistics method efficiently parses statistics from a string format. The use of generics and the FromStr trait ensures flexibility and type safety. However, consider adding error logging or a debug statement for cases where parsing fails, to aid in debugging and maintainability.

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

The test cases are well-organized and cover a variety of scenarios, ensuring that the QueryResult methods function as expected. Consider adding a test case to verify the behavior when no statistics are available, to ensure that the methods handle empty or incorrect stats gracefully.
Would you like me to help by adding this test case?
Some functionality was missing, also renamed from FalkorResponse to QueryResult and created a type alias to maintain BC
