Cairo If Let and While Let

Overview

Use if let and while let for concise pattern matching when only one pattern matters.

Quick Use

• Read references/if-let-while-let.md before answering.
• Show the equivalent match when explaining tradeoffs.
• Mention that if let can include an else branch.

Response Checklist

• Use if let pattern = expr { ... } for single-variant matches.
• Use while let pattern = expr { ... } to loop while a pattern matches.
• Note that these forms are not exhaustive and can hide missing cases.

Example Requests

• "How do I unwrap Option::Some with if let?"
• "How do I loop while pop_front returns Some?"
• "When should I prefer match instead of if let?"
