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)

Document Invariants and State Space for Function Scheduling Apparatus

This pull request updates the documentation in rust/s3heap-service/README.md to elaborate on the invariants and state transition logic of the function scheduling system. The state space is extended to include consideration of function templates in addition to previously documented heap and sysdb states. The documentation introduces new tables and a comprehensive state transition diagram, along with detailed descriptions of invariants and edge cases, to formalize system behaviors and transitions.

Key Changes

• Replaced references to task manager and tasks with function manager and functions for system model clarity.
• Added explicit consideration of function templates in the system state space.
• Expanded and restructured state space explanations with new tables, capturing combinations of heap status, sysdb status, and function template presence.
• Removed the previous state transition table in favor of a more detailed matrix that includes invariants, transitional actions, and impossible states.
• Added detailed explanations for each invariant, edge case, and action in state transitions.
