std::basic_spanbuf::span(3)    C++ Standard Libary   std::basic_spanbuf::span(3)

NAME
     std::basic_spanbuf::span - std::basic_spanbuf::span

Synopsis
	std::span<CharT> span() const noexcept;   (1) (since C++23)
	void span( std::span<CharT> s ) noexcept; (2) (since C++23)

	1) Gets a span referencing the written area if std::ios_base::out is set
     in the open
	mode, or a span referencing the underlying buffer otherwise.
	2)  Makes  the	basic_spanbuf perform I/O on the buffer referenced by s.
     Sets pointers
	to get area, put area, or both.

Parameters
	s - a std::span that references the user-provided buffer

Return value
	1) std::span<CharT>(pbase(), pptr()) if std::ios_base::out is set in the
     open mode,
	or a std::span<CharT> that references the whole underlying buffer other-
     wise.
	2) (none)
