description: Explain Cairo Array usage, ArrayTrait methods, array! macro, Span, and array read/write constraints; use when a request involves creating, updating, reading, or passing arrays in Cairo.

Cairo Arrays

Overview

Explain Cairo Array semantics, method choices, and safe access patterns.

Quick Use

  • •Read references/arrays.md before answering.
  • •Provide minimal, compile-ready snippets using ArrayTrait or array!.
  • •Call out whether get or at is appropriate for bounds safety.

Response Checklist

  • •Use ArrayTrait::new() or array![] to construct arrays.
  • •Use append to add to the end and pop_front to remove from the front.
  • •Use get for Option-based bounds handling; use at or arr[index] when panicking is desired.
  • •Mention Span when read-only views are needed.

Example Requests

  • •"Why can't I modify an element in a Cairo array?"
  • •"When should I use get vs at?"
  • •"How do I create an array literal?"
