Order statistic map with compact storage, calculates the rank of elements. See orbtree and orbtreemap for description of members.
| Key | Key to sort elements by. |
| Value | Value stored in elements. |
| NVType | Integer type for rank calculation. |
| IndexType | unsigned integral type to use for indexing. Maximum number of elements is half of the maximum value of this type - 1. Default is uin32_t, i.e. 32-bit integers, allowing 2^31-1 elements. |
| Compare | Comparison functor for keys. |
Note: internally, it uses realloc_vector::vector if both Key and Value are trivially copyable (as per std::is_trivially_copyable) and stacked_vector::vector otherwise. In the latter case, performnace can be improved by using the libdivide library – see the documentation of stacked_vector for more details.
