Cairo Functions

Overview

Guide users through Cairo function definitions, calls, return values, and const functions with correct syntax and typing.

Quick Use

• Read references/functions.md before answering.
• Show minimal, compile-ready snippets with correct parameter and return type annotations.
• Call out statement vs expression rules when return values are involved.

Response Checklist

• Include parameter types and return types where required.
• If returning a value, use a tail expression without a semicolon or an explicit return.
• If the user mentions named arguments, show foo(x: value) or foo(:x).

Example Requests

• "How do I return a value from a Cairo function?"
• "Can I call a function with named arguments?"
• "What is a const fn in Cairo?"
