name: cairo-match description: Explain Cairo match expressions, pattern matching on enums, exhaustiveness, and wildcard arms; use when a request involves matching Option/Result or enum values in Cairo.

Cairo Match

Overview

Explain how to use match for branching on enum values and destructuring data safely.

Quick Use

• Read references/match.md before answering.
• Include an exhaustive match with a _ fallback when appropriate.
• Emphasize that all arms must return the same type when used as an expression.

Response Checklist

• Use fully qualified variants like EnumName::Variant in patterns.
• Bind inner data with patterns like EnumName::Variant(value).
• Keep match arms exhaustive; add _ only when appropriate.

Example Requests

• "How do I match on an Option in Cairo?"
• "Why is my match non-exhaustive?"
• "How do I extract the value from an enum variant?"
