Ast_helper.Mtd(3)

💅 Ast_helper.Mtd — the OCaml library manual page, but make it group chat

Okay so this is from the OCaml library manual, section 3, and it's literally all about module type declarations. Buckle up bestie, it's a short one but we're gonna treat it with the respect it deserves 🫶

✨ NAME ✨

Ast_helper.Mtd — Module type declarations 👑

---

🦋 Module 🦋

Module Ast_helper.Mtd

That's the whole vibe. It's a module. It has a name. Iconic behaviour, honestly.

---

📚 Documentation 📚

So inside, we've got:

Module Mtd
 : sig end

Yep — Module Mtd with : sig end. That's the entire signature, and it's giving minimalist main character energy ✨

Then the page tells us what this module is for, plain and simple:

Module type declarations 🎀

And here's the one value chilling in there — the mk function, signature delivered exactly as written, no cap:

val mk : ?loc:Ast_helper.loc -> ?attrs:Ast_helper.attrs ->
?docs:Docstrings.docs -> ?text:Docstrings.text ->
?typ:Parsetree.module_type -> Ast_helper.str ->
Parsetree.module_type_declaration

Look at all those optional labelled arguments — ?loc, ?attrs, ?docs, ?text, ?typ — followed by a required Ast_helper.str and handing you back a Parsetree.module_type_declaration. The way that type signature just flows 😭💖

Lowkey reminder: this page gives you the signature and the one-liner description and that's it. No extra lore, no hidden tips — what you see is what you get, bestie. 🫶

✨ that's the whole page ✨
