name	cairo-structs-example
description	Explain the Cairo example program that refactors rectangle area calculations into a struct, including `Into`/`TryInto` conversions; use when a request references the Chapter 5.2 struct example or asks for struct-based refactors.

Cairo Structs Example

Overview

Guide refactoring patterns from separate variables to tuples to structs, and show conversions between related structs.

Quick Use

• Read references/structs-example.md before answering.
• Use the Rectangle example to illustrate why structs improve clarity.
• Include conversion trait usage (Into, TryInto) when discussing type transformations.

Response Checklist

• Show how struct fields make code self-documenting.
• If converting types, mention that .into() needs a target type context.
• For fallible conversions, show TryInto returning Option or Result.

Example Requests

• "Can you refactor these width/height variables into a struct?"
• "How do I convert between two struct types in Cairo?"
