Module stateful_bi_consumer 

BiConsumer Types

Provides bi-consumer interface implementations for operations accepting two input parameters without returning a result.

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

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

• BoxStatefulBiConsumer<T, U>: Box-based single ownership for one-time use
• ArcStatefulBiConsumer<T, U>: Arc<Mutex<>>-based thread-safe shared ownership
• RcStatefulBiConsumer<T, U>: Rc<RefCell<>>-based single-threaded shared ownership

Design Philosophy

BiConsumer uses FnMut(&T, &U) semantics: can modify its own state but does NOT modify input values.

Suitable for statistics, accumulation, and event processing scenarios involving two parameters.
