Rusty thoughts on "Parse, don't validate"
This article explores the 'Parse, don't validate' programming pattern within the context of the Rust language. It discusses how to leverage type systems to enforce invariants, reducing the need for runtime checks.
Why it matters
Adopting this pattern can lead to more robust, bug-free software by catching errors at compile-time rather than runtime.
Like many programmers, I find Alexis King's Parse, don't validate article fascinating, because it gives a name to an idiom that seems familiar and important - one I've observed and used in the past without naming it explicitly. This post is a review of the "Parse, don't validate" pattern applied to the Rust programming language (the original post uses Haskell). I was particularly interested in finding educational examples of this pattern in the Rust standard library and other well-known projects.
Without repeating the original article (please read it first!), here's the gist of it.
