Matt Godbolt sold me on Rust (by showing me C++)

- Matt Godbolt's talk on Correct by Construction APIs highlights the challenges in C++ with type safety and how Rust addresses these issues more effectively.
- In C++, even with type aliasing and explicit constructors, it's still possible to misuse types like Quantity and Price without compiler warnings.
- Rust's type system and compiler checks prevent common mistakes, such as swapping argument types or using negative values for unsigned integers, at compile time.
- Rust's handling of runtime input errors, like parsing strings to numbers, forces developers to handle potential errors explicitly, improving code safety.
- The article emphasizes that Rust's design benefits go beyond memory safety, helping developers avoid simple mistakes and write more reliable code.
