| Method | Description | 
| inline size_type get_init_size (size_type suggested_size) const | Given suggested_size, a suggested size, returns an initial size of the container related to the initial size. | 
| inline size_type get_nearest_larger_size (size_type cur_size) const | Given cur_size, the current size, returns a size that is larger. | 
| inline size_type get_nearest_smaller_size (size_type cur_size) const | Given cur_size, the current size, returns a size that is smaller. |
