Summary
The post discusses techniques for tracking the origin of Rust errors, specifically how to utilize `anyhow` for error handling and debugging with `std::io::Error`. It advises setting multiple breakpoints for various constructors of the error type to identify where errors are created, as some libraries may not provide a detailed error trace out-of-the-box.
