It is possible to extract code coverage from Rust code (https://github.com/xd009642/tarpaulin, https://medium.com/@Razican/continuous-integration-and-code-coverage-report-for-a-rust-project-5dfd4d68fbe5, https://github.com/kennytm/cargo-kcov, etc.). It is also possible to get code coverage data for Firefox out of the automated test runs that happen (https://developer.mozilla.org/en-US/docs/Mozilla/Testing/Measuring_Code_Coverage_on_Firefox). It would be useful to figure out if we can make this data available for Servo.
