# Cairo Method Syntax
## Overview
Guide method definitions using traits and impl blocks, with correct `self` forms.
## Quick Use
- Read `references/method-syntax.md` before answering.
- Show a small struct with an impl block and a method taking `self` or `@self`.
- Mention associated functions for constructors like `new` or `square`.
## Response Checklist
- Use `self` by value for ownership-taking methods.
- Use `@self` for read-only methods and `ref self` for mutation.
- Note that methods are defined in traits and implemented in `impl` blocks.
## Example Requests
- "How do I define a method on a Cairo struct?"
- "What's the difference between `self`, `@self`, and `ref self`?"
- "How do I write a constructor-like associated function?"
