/// Creates a handler implementation with boilerplate code.
///
/// This macro generates a struct that implements the `Base` trait,
/// automatically providing the required boilerplate for handler creation.
///
/// # Syntax
///
/// ```ignore
/// handler! {
///     StructName, handler_name;
///     async fn run(&self, src: String, data: String) -> Result<String, Box<dyn Error + Send + Sync>> {
///         // Your handler logic here
///     },
///     // Additional methods (optional)
/// }
/// ```
///
/// # Example
///
/// ```ignore
/// handler! {
///     MyHandler, my_handler;
///     async fn run(&self, src: String, data: String) -> Result<String, Box<dyn Error + Send + Sync>> {
///         Ok(format!("Processed: {}", data))
///     }
/// }
/// ```
