Module mapper 

Mapper Types

Provides Rust implementations of mapper traits for stateful value transformation. Mappers consume input values (taking ownership) and produce output values while allowing internal state modification.

This module provides the Mapper<T, R> trait and three implementations:

• BoxMapper: Single ownership, not cloneable
• ArcMapper: Thread-safe shared ownership, cloneable
• RcMapper: Single-threaded shared ownership, cloneable
