std::inplace_vector<T,N>::capacity
From cppreference.com
< cpp | container | inplace vector
|
static constexpr size_type capacity() noexcept;
|
(since C++26) | |
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
Run this code
#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); }
