description: Explain Cairo smart pointers, especially Box types, boxed memory segments, and recursive types; use when a request involves boxing values, avoiding copies, or defining recursive types in Cairo.

Cairo Smart Pointers

Overview

Explain how smart pointers manage memory safely, with a focus on Box<T>.

Quick Use

  • •Read references/smart-pointers.md before answering.
  • •Use BoxTrait::new and unbox() in examples.
  • •Highlight when boxing is necessary (recursive types, large values).

Response Checklist

  • •Explain that arrays and dictionaries are smart pointers owning memory segments.
  • •Use Box<T> to store data in the boxed segment and move only pointers.
  • •Use boxes to break recursive type size issues.

Example Requests

  • •"How do I make a recursive enum compile?"
  • •"When should I use Box in Cairo?"
  • •"How do I access a boxed value?"
