[inplace.vector.capacity]

static constexpr size_type capacity() noexcept;
static constexpr size_type max_size() noexcept;

Returns: N.

constexpr void resize(size_type sz);

Effects: If sz < size(), erases the last size() - sz elements from the sequence.

Otherwise, appends sz - size() default-inserted elements to the sequence.

Remarks: If an exception is thrown, there are no effects on *this.

constexpr void resize(size_type sz, const T& c);

Effects: If sz < size(), erases the last size() - sz elements from the sequence.

Otherwise, appends sz - size() copies of c to the sequence.

Remarks: If an exception is thrown, there are no effects on *this.

static constexpr void reserve(size_type n);

Throws: bad_alloc if n > capacity() is true.

static constexpr void shrink_to_fit() noexcept;

Effects: None.
