//! # Supplier Clone Macro
//!
//! Generates Clone trait implementation for basic Supplier types
//!
//! Generates Clone implementation for Supplier structs that have `function`
//! and `name` fields. The function field is cloned using its inherent `clone`
//! method, which performs a shallow clone for smart pointers like `Arc` or
//! `Rc`.
//!
//! # Parameters
//!
//! * `$struct_name` - The struct name
//! * `$generic` - Generic parameter list (one type parameter)
//!
//! # Examples
//!
//! The example requires the `rc` and `stateful` features.
//!
//! ```rust
//! # #[cfg(all(feature = "rc", feature = "stateful"))]
//! # {
//! use qubit_function::{ArcStatefulSupplier, ArcSupplier, RcStatefulSupplier, RcSupplier, Supplier};
//!
//! let arc = ArcSupplier::new(|| 1);
//! let arc_clone = arc.clone();
//! assert_eq!(arc_clone.get(), 1);
//!
//! let rc = RcSupplier::new(|| "ok".to_string());
//! let rc_clone = rc.clone();
//! assert_eq!(rc_clone.get(), "ok".to_string());
//!
//! let stateful_arc = ArcStatefulSupplier::new(|| 1);
//! let _stateful_arc_clone = stateful_arc.clone();
//!
//! let stateful_rc = RcStatefulSupplier::new(|| 1);
//! let _stateful_rc_clone = stateful_rc.clone();
//! # }
//! ```
/// Generates Clone trait implementation for basic Supplier types
///
/// This macro should be used at the top level (outside of any impl block) as

/// Clone implementation for Supplier structs that have `function` and `name`
/// fields. The function field is cloned using its inherent `clone` method,
/// which performs a shallow clone for smart pointers like `Arc` or `Rc`.
///
/// # Parameters
///
/// * `$struct_name` - The struct name
/// * `$t` - Generic parameter list (one type parameter)
///
/// # Examples

/// ```rust
