Where is `class vector` implemented in libcxx?

Question

I would like to find the implementation of class vector in libcxx. However, in the header file vector of libcxx, https://github.com/llvm/llvm-project/blob/main/libcxx/include/vector , there is only class vector defined in comment region, instead of in source region.

Where is class vector really defined?

class _LIBCPP_TEMPLATE_VIS vector
    : private __vector_base<_Tp, _Allocator>
{
