Module readonly_consumer 

ReadonlyConsumer Types

Provides implementations of readonly consumer interfaces for executing operations that neither modify their own state nor modify input values.

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

• BoxReadonlyConsumer<T>: Box-based single ownership implementation
• ArcReadonlyConsumer<T>: Arc-based thread-safe shared ownership implementation
• RcReadonlyConsumer<T>: Rc-based single-threaded shared ownership implementation

Design Philosophy

ReadonlyConsumer uses Fn(&T) semantics, neither modifying its own state nor modifying input values. Suitable for pure observation, logging, notification and other scenarios. Compared to Consumer, ReadonlyConsumer does not require interior mutability (Mutex/RefCell), making it more efficient and easier to share.
