| # Code style |
| |
| ## Java |
| |
| Run the Spotless formatter before committing. CI fails the build if |
| formatting drifts: |
| |
| ```sh |
| ./mvnw spotless:apply |
| ``` |
| |
| ## Rust |
| |
| Run inside `native/`: |
| |
| ```sh |
| cargo fmt |
| cargo clippy --all-targets -- -D warnings |
| ``` |
| |
| `-D warnings` turns clippy warnings into build failures, matching CI. |
| |
| ## License headers |
| |
| New source files need the Apache 2.0 license header. Apache RAT enforces |
| this during `verify` — `./mvnw verify` will fail if a tracked file is |
| missing the header. |
