## Build & Development Commands
- Follow Rust coding standards
- Avoid unsafe features
- Use Result and Option to handle errors explicitly.
- Use tokio-based asynchronous processing as the default, but avoid it in ECS 
 logic system functions where builds are likely to break; instead, use tokio bounded channels. Only in areas with potential performance bottlenecks, and employ rayon’s par_iter for parallelization when needed.
- Use function and variable names that clearly convey intent, and break logic into small units.

## Testing Guidelines
- Write unit tests for all major functions and regularly verify them with cargo test.
- If tests are anticipated to require significant execution time, use the #[tokio::test] attribute to support asynchronous testing with tokio.

## Code Style & Guidelines 
- Write it according to the cargo fmt format.

## Documentation Guidelines 
- Add Rustdoc comments (///) to public APIs to provide usage instructions and examples.
