std::inplace_vector<T,N>:: capacity

Returns the capacity of the internal (inplace) storage. Equivalent to: return N ; .

Parameters

(none)

Return value

The maximum number of elements the container is able to hold.

Complexity

Constant.

Notes

Because each std:: inplace_vector < T, N > is a fixed-capacity container, the value returned by capacity equals N (which is also the value returned by max_size() ).

Example

#include <inplace_vector>
 
int main()
{
    constexpr std::inplace_vector<int, 4> v1;
    static_assert(v1.capacity() == 4 && v1.max_size() == 4);
 
    constexpr std::inplace_vector<int, 0> v2;
    static_assert(v2.capacity() == 0 && v2.max_size() == 0);
}
