Parse:...straint(3pm)

✨ Parse::Method::Signatures::TypeConstraint(3pm) ✨

okay bestie, so this is a page from the User Contributed Perl Documentation, and it's giving very specific niche utility and honestly? we're obsessed 💅

---

🎀 NAME 🎀

Parse::Method::Signatures::TypeConstraint — the little glow-up machine that turns parsed TC data into a Moose TC object 💖

---

🌸 DESCRIPTION 🌸

So basically, this is the class that takes your PPI elements and transforms them into Moose::Meta::TypeConstraint objects. It's the fairy godmother of type constraints, no cap 🧚✨

---

🦋 ATTRIBUTES 🦋

💜 tc

Lazy Build, periodt.

This is the Moose::Meta::TypeConstraint object for this type constraint — and it only gets built when someone actually asks for it. And when it does get built? tc_callback gets called for each individual component type, one at a time, in turn. Patient. Methodical. Iconic. 👑

💜 tc_callback

• Type: CodeRef
• Default: find_registered_constraint

This is the callback that turns type names into type objects. If you want the full tea plus an actual example, go peek at type_constraint_callback in Parse::Method::Signatures. iykyk 📖✨

💜 from_namespace

• Type: ClassName

If you pass this in, then the default tc_callback will go searching for MooseX::Types in this package. She's thorough like that 🕵️♀️💅

---

🌈 METHODS 🌈

⭐ find_registered_constraint

This one will search for an imported MooseX::Types inside from_namespace — but only if you actually provided one. If that doesn't pan out, she goes and asks the Moose::Meta::TypeConstraint::Registry for a type with the given name.

And if all of that fails? She just returns the type as a string, so that Moose's auto-vivification of classnames to type will work. Lowkey a fallback queen 🙈💖

⭐ to_string

String representation of the type constraint, approximately as parsed. Approximately! She's not doing a whole makeover, just showing you the vibe 🌸
