Reviewer Checklist

Please leverage this checklist to ensure your code review is thorough before approving

Testing, Bugs, Errors, Logs, Documentation

• Can you think of any use case in which the code does not behave as intended? Have they been tested?
• Can you think of any inputs or external events that could break the code? Is user input validated and safe? Have they been tested?
• If appropriate, are there adequate property based tests?
• If appropriate, are there adequate unit tests?
• Should any logging, debugging, tracing information be added or removed?
• Are error messages user-friendly?
• Have all documentation changes needed been made?
• Have all non-obvious changes been commented?

System Compatibility

• Are there any potential impacts on other parts of the system or backward compatibility?
• Does this change intersect with any items on our roadmap, and if so, is there a plan for fitting them together?

Quality

• Is this code of a unexpectedly high quality (Readability, Modularity, Intuitiveness)

Enable ASAN build path adjustments in rust/Dockerfile

Updates to rust/Dockerfile make the AddressSanitizer build path functional by switching RUSTFLAGS to ${ADDRESS_SANITIZER:+'-Z sanitizer=address'} and computing a conditional build_target so cargo uses --target x86_64-unknown-linux-gnu whenever ASAN is requested.

The binary packaging step now derives the correct target subdirectory for sanitizer builds and replaces the repeated mv commands with a loop that moves each service binary from the computed build directory.

Key Changes

• Set RUSTFLAGS via ${ADDRESS_SANITIZER:+'-Z sanitizer=address'} to ensure the sanitizer flag is applied only when requested
• Introduced build_target and sanitization-aware build_dir variables so cargo build emits artifacts in the correct target triple directory under ASAN
• Collapsed individual mv statements into a for loop that copies all service binaries from target/${build_dir}

Affected Areas

• rust/Dockerfile
• Rust build pipeline
• ASAN-enabled Docker builds

[Maintainability] To avoid repeating the long cargo build command, you can use command substitution to conditionally add the --release flag. This makes the line more concise and easier to maintain.
