| readability-container-data-pointer |
| ================================== |
| |
| Finds cases where code could use ``data()`` rather than the address of the |
| element at index 0 in a container. This pattern is commonly used to materialize |
| a pointer to the backing data of a container. ``std::vector`` and |
| ``std::string`` provide a ``data()`` accessor to retrieve the data pointer which |
| should be preferred. |
| |
| This also ensures that in the case that the container is empty, the data pointer |
| access does not perform an errant memory access. |
