name	cairo-arrays
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?"
