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?"
