/// Internal namespace.
mod internal {}

/// Derive macro for `CloneDyn` trait.
///
/// It is a procedural macro that generates an implementation of the `CloneDyn` trait for a given type.
///
/// ### Sample.
///
/// ```rust
/// #[ cfg( feature = "derive_clone_dyn" ) ]
/// #[ clone_dyn ]
/// pub trait Trait1
/// {
///   fn f1( &self );
/// }
///
/// #[ cfg( feature = "derive_clone_dyn" ) ]
/// #[ clone_dyn ]
/// pub trait Trait2: Trait1
/// {
///   fn f2( &self );
/// }
/// ```
///
/// To learn more about the feature, study the module [`clone_dyn`](https://docs.rs/clone_dyn/latest/clone_dyn/).
