description: Explain how components are expanded under the hood, including HasComponent and ComponentState; use when a request involves debugging or understanding generated component code in Cairo.

Cairo Components Under the Hood

Overview

Explain the generated traits and wrappers created by component macros and how they connect to the host contract.

Quick Use

  • •Read references/components-under-hood.md before answering.
  • •Mention HasComponent methods for access and mutation.
  • •Explain how embeddable impls become contract entry points.

Response Checklist

  • •Identify the generated HasComponent trait and its methods.
  • •Explain ComponentState<TContractState> as the bridge to host storage.
  • •Clarify how impl aliases and #[abi(embed_v0)] expose entry points.

Example Requests

  • •"What does component! generate behind the scenes?"
  • •"How does ComponentState work?"
  • •"Why do I need HasComponent for embedding?"
