//! # Conditional Consumer Debug Display Macro
//!
//! Generates Debug and Display trait implementations for Conditional Consumer structs
//!
//! Generates standard Debug and Display trait implementations for Conditional
//! Consumer structs that have `consumer` and `predicate` fields but no `name` field.
//!
//! # Parameters
//!
//! * `$struct_name` - The struct name
//! * `$generic` - Generic parameter list (one or more type parameters)
//!
//! # Examples
//!
//! ```rust
//! use qubit_function::consumers::bi_consumer::BoxConditionalBiConsumer;
//! use qubit_function::consumers::consumer::BoxConditionalConsumer;
//! macro_rules! impl_conditional_consumer_debug_display {
//!     ($struct_name:ident<$t:ident>) => {
//!         let _ = core::marker::PhantomData::<$t>;
//!         let _ = stringify!($struct_name);
//!     };
//!     ($struct_name:ident<$t:ident, $u:ident>) => {
//!         let _ = core::marker::PhantomData::<($t, $u)>;
//!         let _ = stringify!($struct_name);
//!     };

/// Generates Debug and Display trait implementations for Conditional Consumer structs
///
/// This macro should be used at the top level (outside of any impl block) as
/// it generates complete `impl Debug` and `impl Display` blocks for the
/// specified struct. Generates standard Debug and Display trait implementations
/// for Conditional Consumer structs that have `consumer` and `predicate` fields
/// but no `name` field.
///
/// # Parameters
///
/// * `$struct_name` - The struct name
/// * `$t` - Generic parameter list (one or more type parameters)
/// * `u` - Generic parameter list (one or more type parameters)
///
/// # Examples
///
/// ```rust
/// // For single type parameter
/// use qubit_function::consumers::bi_consumer::BoxConditionalBiConsumer;
/// use qubit_function::consumers::consumer::BoxConditionalConsumer;
/// macro_rules! impl_conditional_consumer_debug_display {
///     ($struct_name:ident<$t:ident>) => {
///         let _ = core::marker::PhantomData::<$t>;
///         let _ = stringify!($struct_name);
///     };

///         let _ = stringify!($struct_name);
///     };
