Cairo Procedural Macros

Overview

Guide how to create and use procedural macros implemented in Rust for Cairo.

Response Checklist

  • •Use TokenStream input and ProcMacroResult output.
  • •Mark functions with #[inline_macro], #[attribute_macro], or #[derive_macro].
  • •Configure Cargo.toml with crate-type = ["cdylib"] and cairo-lang-macro deps.
  • •Add [cairo-plugin] in Scarb.toml.
