Rusty thoughts on "Parse, don't validate"

The article argues that IT and software teams should prefer transforming raw data into types that encode business rules, rather than simply validating values and carrying hidden assumptions forward. In Rust, replacing a plain `Vec` with a `NonEmpty` type eliminates repeated null/empty checks, makes code safer and clearer, and reduces the risk of downstream failures if invariants change—an approach that can improve reliability, maintainability, and performance in production systems. For CIOs and technology leaders, the strategic takeaway is that stronger domain types shift correctness left into the design of APIs and services, lowering operational risk and simplifying long-term system evolution.
