std::inplace_vector<T,N>::empty
constexpr bool empty() const noexcept; | (since C++26) |
Checks if the container has no elements, i.e., whether begin() == end().
Return value
true if the container is empty, false otherwise.
Complexity
Constant.
Example
#include <cassert>
#include <inplace_vector>
int main()
{
std::inplace_vector<char, 8> v;
assert(v.empty());
v.push_back('_');
assert(not v.empty());
}
