Module stateful_consumer 

Consumer Types

Provides implementations of consumer interfaces for executing operations that accept a single input parameter but return no result.

It is similar to the FnMut(&T) trait in the standard library.

This module provides a unified Consumer trait and three concrete implementations based on different ownership models:

• BoxStatefulConsumer<T>: Box-based single ownership implementation for one-time use scenarios
• ArcStatefulConsumer<T>: Thread-safe shared ownership implementation based on Arc<Mutex<>>
• RcStatefulConsumer<T>: Single-threaded shared ownership implementation based on Rc<RefCell<>>

Design Philosophy

Consumer uses FnMut(&T) semantics, allowing modification of its own state but not the input value.

Suitable for statistics, accumulation, event handling, and other scenarios.
