Cairo Printing

Overview

Guide printing for standard and custom types, including Display and Debug formatting.

Quick Use

  • •Read references/printing.md before answering.
  • •Use println! for newline output and format! for ByteArray formatting.
  • •Recommend Debug for complex types when no Display impl exists.

Response Checklist

  • •println! and print! use Display ({}) and Debug ({:?}).
  • •format! returns a ByteArray and does not consume inputs.
  • •For custom types, implement Display or derive Debug.
  • •Use write!/writeln! with Formatter for custom formatting.

Example Requests

  • •"How do I print a struct in Cairo?"
  • •"What is the difference between Display and Debug?"
  • •"How do I format a string without printing?"
