Front-window bakery material. Catches the eye, delivers the goods.
Summary
This article explores the "Parse, don't Validate" programming pattern and type-driven design principles in the context of Rust programming. It discusses how to avoid validation functions by encoding invariants at the type level, drawing from a Haskell-based concept but applying it specifically to Rust. The article addresses the challenge of explaining these functional programming concepts to Rust developers and provides practical guidance on implementing type-driven design patterns in Rust APIs.

· 4 pulledIn the Rust Programming Language Community Server, there's tag named -parse-dont-validate which links to an article about the concept of avoiding validation functions and encoding invariants in the type level instead.
I usually recommend it to beginners/intermediates to Rust who are struggling with designing APIs.
The only problem is that it uses Haskell to explain its concepts.
