Custom Type Traits vs Runtime Type Information

Developers should learn Custom Type Traits when working with template-heavy C++ code, such as in libraries like the Standard Template Library (STL) or Boost, to create more flexible and efficient generic algorithms meets developers should learn and use rtti when building applications that require dynamic polymorphism, such as in frameworks for serialization, reflection, or debugging tools where object types need to be determined at runtime. Here's our take.

Custom Type Traits

Developers should learn Custom Type Traits when working with template-heavy C++ code, such as in libraries like the Standard Template Library (STL) or Boost, to create more flexible and efficient generic algorithms

Custom Type Traits

Nice Pick

Developers should learn Custom Type Traits when working with template-heavy C++ code, such as in libraries like the Standard Template Library (STL) or Boost, to create more flexible and efficient generic algorithms

Pros

  • +They are essential for tasks like type introspection, conditional compilation, and optimizing code paths based on type properties, such as checking if a type is integral, pointer, or has certain member functions
  • +Related to: cplusplus-templates, template-metaprogramming

Cons

  • -Specific tradeoffs depend on your use case

Runtime Type Information

Developers should learn and use RTTI when building applications that require dynamic polymorphism, such as in frameworks for serialization, reflection, or debugging tools where object types need to be determined at runtime

Pros

  • +It is essential in scenarios involving heterogeneous collections, plugin architectures, or when implementing design patterns like Visitor or Factory, as it allows for safe type conversions and error handling without hardcoding type checks
  • +Related to: object-oriented-programming, polymorphism

Cons

  • -Specific tradeoffs depend on your use case

The Verdict

Use Custom Type Traits if: You want they are essential for tasks like type introspection, conditional compilation, and optimizing code paths based on type properties, such as checking if a type is integral, pointer, or has certain member functions and can live with specific tradeoffs depend on your use case.

Use Runtime Type Information if: You prioritize it is essential in scenarios involving heterogeneous collections, plugin architectures, or when implementing design patterns like visitor or factory, as it allows for safe type conversions and error handling without hardcoding type checks over what Custom Type Traits offers.

🧊
The Bottom Line
Custom Type Traits wins

Developers should learn Custom Type Traits when working with template-heavy C++ code, such as in libraries like the Standard Template Library (STL) or Boost, to create more flexible and efficient generic algorithms
