Explore the intricacies of error handling in C++ through this comprehensive conference talk from ACCU 2017. Delve into various error handling techniques, including enums, exceptions, and the system_error header. Compare C++'s approach with newer languages like Rust and Swift, which use monadic wrappers for error handling. Examine the ongoing efforts to standardize error handling in C++, including optional and expected. Discover a new solution called "outcomes," implemented as Boost.Outcome library, which offers a lightweight alternative for unified error handling. Learn about the performance implications of different error handling methods across major compilers and library implementations. Gain insights into the potential future of error handling in C++ and its implications for game development and low-latency applications.
