Ok, so if you did want to reuse span<byte> as any future std::file_handle::buffer_type, the following program would compile: ``` #include <span> #include <type_traits> #include <sys/uio.h> using buffer_type = std::span<std::byte>; static_assert(sizeof(buffer_type) == sizeof(struct iovec)); static_assert(std::is_trivially_copyable_v<buffer_type>); static_assert(std::is_standard_layout_v<buffer_type>); static_assert(std::is_layout_compatible_v<buffer_type, struct iovec>); ```
