Error Handling Strategy

To ensure critical error propagation in Python, implement a mandatory bubbling strategy that prevents exceptions like OSError, RuntimeError, SystemExit, KeyboardInterrupt, and MemoryError from being caught.

The best way to handle exceptions in Rust for reliability is using Result<T, Error> based propagation, explicitly avoiding .unwrap() calls to safely manage critical errors without crashing.

You structure a custom exception hierarchy by inheriting domain-specific types like ValidationError, ParsingError, and OCRError from a base application error, ensuring consistent categorization across your codebase.

Subprocess errors are silently ignored when stderr is not parsed and mapped to a critical exception type, a scenario this error handling strategy prevents by explicitly identifying and propagating these failures.

Yes, you can use a unified error handling strategy across both languages by applying language-specific implementations: exception-based inheritance in Python and Result-based propagation in Rust.

You should not use .unwrap() in Rust when building critical applications, as it causes immediate crashes instead of safely propagating errors via the Result<T, Error> type for reliable recovery.
