hook_field_views_data(\Drupal\field\FieldStorageConfigInterface $field_storage)
Override the default Views data for a Field API field.
The field module's implementation of hook_views_data() invokes this for each field storage, in the module that defines the field type. It is not invoked in other modules.
If no hook implementation exists, hook_views_data() falls back to views_field_default_views_data().
Parameters
\Drupal\field\FieldStorageConfigInterface $field_storage: The field storage config entity.
Return value
array An array of views data, in the same format as the return value of hook_views_data().
