A Practical Approach to Error Handling

Explore a practical approach to error handling in this conference talk from ACCU 2022. Learn about a refined method for managing errors in software development, balancing reliability and complexity. Discover how to categorize errors, implement exception safety guarantees, and analyze error causes. Gain insights into critical errors, untested scenarios, and user experience issues. Understand the concept of minimum description length for error reporting and explore C++20 contracts. Apply these techniques to write more reliable software with less effort in your next project.
