23-24: Updated imports to reflect renaming and new type addition. This aligns with the PR's objective to streamline naming conventions.
36-36: The instantiation ofDefaultMappedFilehere is correct and uses the new class as expected. Ensure that the methodDefaultMappedFile::newhandles the parameters correctly, especially the conversion fromOsStringtoString.Verification successful
The
DefaultMappedFile::newmethod implementations found inrocketmq-store/src/log_file/mapped_file/default_impl.rshandleStringparameters directly. There is no conversion fromOsStringtoStringwithin these methods. Therefore, the instantiation ofDefaultMappedFilein the provided code snippet should be correct as long as it providesStringparameters.
rocketmq-store/src/log_file/mapped_file/default_impl.rs: Verified that thenewmethod implementations handleStringparameters directly.Scripts executed

27-27: The import statement has been correctly updated to useDefaultMappedFileinstead ofLocalMappedFile. This change is consistent with the renaming strategy described in the PR summary.
110-110: TheAllocateRequeststruct has been updated to useDefaultMappedFilefor themapped_filefield. This change is necessary for the consistency of type usage across the project.rocketmq-store/src/queue/batch_consume_queue.rs (2)
33-33: The import statement has been correctly updated to reflect the new typeDefaultMappedFile. This ensures consistency across the project.
76-77: The fieldsoffset_cacheandtime_cacheinBatchConsumeQueuehave been updated to useDefaultMappedFile. This change is part of the renaming and reorganization effort to enhance code clarity.rocketmq-store/src/log_file/mapped_file/default_impl.rs (1)
712-717: Implementation of theDefaulttrait forReferenceResourceis a good addition, providing a clean default constructor method for this type.

The method signature correctly reflects the use of DefaultMappedFile. However, ensure that the unimplemented!() placeholder is addressed before merging this PR.
Consider implementing the method or marking it with a TODO if it's to be implemented later.
