description: Explain Cairo method syntax, traits/impl blocks, `self` parameter forms, and associated functions; use when a request involves defining or calling methods on structs in Cairo.

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?"
