   # rosidl_runtime_cpp Features
   
   ## Typesupport function handler  
   
   `rosidl_runtime_cpp` provides several templated function declarations for getting the type support handler.
   They are meant to be defined in each rosidl definition's C++ generated code.
   They are defined for both the `rosidl_runtime_cpp` and `rosidl_typesupport_cpp` namespaces.
   
   `rosidl_runtime_cpp`
   * Messages (`message_type_support_decl.hpp`)
   * Services (`service_type_support_decl.hpp`)
   * Actions (`action_type_support_decl.hpp`)
   
   `rosidl_typesupport_cpp`
   * Messages (`message_type_support.hpp`)
   * Services (`service_type_support.hpp`)
   * Actions (`action_type_support.hpp`)
   
   ## C++ Type Traits
   
   `rosidl_runtime_c` provides numerous C++ Type Traits for rosidl interfaces in `traits.hpp`.
   These type traits are useful for providing compile-time checks of rosidl C++ types.
   
   ## Bounded Vector
   
   Provided in `bounded_vector.hpp` is an implementation of a std::vector like container class, that has a bounded capacity.
   This class is utilized by rosidl types that declare a bounded sequence.
