<!-- Please describe your changes on the following line: --> The code was refactored to follow Rust naming conventions better. --- <!-- Thank you for contributing to Servo! Please replace each `[ ]` by `[X]` when the step is complete, and replace `__` with appropriate data: --> - [x] `./mach build -d` does not report any errors - [x] `./mach test-tidy` does not report any errors - [x] These changes help fix #12379. <!-- Either: --> - [ ] There are tests for these changes OR - [X] These changes do not require tests because logic was not changed. <!-- Pull requests that do not address these steps are welcome, but they will require additional verification as part of the review process. --> Source-Repo: https://github.com/servo/servo Source-Revision: 5457b80233f9ce6773711c7189230d9a0a63d93a
