`bit::matrix` — Capacity Queries

How many rows or columns can the bit-matrix accommodate with any more memory allocations?

1constexpr std::size_t row_capacity() const;
2constexpr std::size_t col_capacity() const;

1: How many rows can be added without a memory allocation?
2: How many columns can be added without a memory allocation?

The rows may not all have the same capacity — the col_capacity() method reports the capacity of the first row.

Example

#include <bit/bit.h>
int main()
{
    bit::matrix<> m(3, 4);
    std::cout << "m.rows():         " << m.rows()           << '\n';
    std::cout << "m.cols():         " << m.cols()           << '\n';
    std::cout << "m.row_capacity(): " << m.row_capacity()   << '\n';
    std::cout << "m.col_capacity(): " << m.col_capacity()   << '\n';
}

Output

m.rows():         3
m.cols():         4
m.row_capacity(): 3
m.col_capacity(): 64
