How does `anyhow!` compare to other error handling crates like `thiserror`?

`anyhow` provides a flexible, dynamic error type with minimal boilerplate. `thiserror` helps generate error enums and boilerplate implementations for custom error types at compile time. Use `anyhow` for quick prototyping and simple applications, and `thiserror` when you need more control over error types and want to optimize for performance.
