💅 DESCRIPTION 💅

Catmandu::Validator::Simple</purl> is literally here for doing simple data validation in Catmandu. That's the whole vibe. No cap. ✨

---

🎀 CONFIGURATION 🎀

handler

A function (yes, a coderef, your moment to shine 👑) that takes a hash reference item as its argument.

The rules of the game, fr fr:

• Should return undef if the record passes validation ✅
• Otherwise return an error or an arrayref of errors 🚩
• Each error can be either:
  • a simple message string, or
  • a hashref to more detailed error information

ngl the "return undef for valid" thing is the whole plot twist — don't forget it or your valid records will be out here getting rejected 😭
