Detailed Description

Convenience macros to explicitly control copy and move semantics.

This header provides a small set of macros that explicitly enable or disable copy and/or move construction and assignment for a class.

The intent is to make ownership and lifetime semantics immediately visible in the class declaration, without repeating boilerplate = delete / = default declarations.

These macros are purely syntactic helpers and do not introduce any additional behavior beyond what is expressed by the generated special member functions.
