prae: a simple library that helps you keep your types valid

Hi! Recently I stumbled upon a post here called Tightness Driven Development. It was an interesting read with very good ideas. The author created a small library called tightness to help users create types that promise to be always valid. Although the library was good, I found it a bit inconvenient and described my concerns in this issue. I didn't get much response, so I decided to write my own (and very first) crate for this!

  prae is a crate that aims to provide a better way to define types that require validation.

Meet prae. It provides a simple proc macro that allows you to do small things like this:

• WorkOS

  workos.com sponsored

  The modern identity platform for B2B SaaS. The APIs are flexible and easy-to-use, supporting authentication, user identity, and complex enterprise features like SSO and SCIM provisioning.

Thanks for the kind words. This is true that proc macro code can be very messy. At first I got some very ugly nested spaghetti code, it took me a couple of iterations to make it a bit more clear. By the way, there is a proposal in syn repo that can make the developer experience even better!
