std::span<charT> span() const noexcept;
Returns: If ios_base::out is set in mode, returns std::span(pbase(), pptr()), otherwise returns buf.
[Note 1:
In contrast to basic_stringbuf, the underlying sequence never grows and is not owned.
An owning copy can be obtained by converting the result to basic_string.

void span(std::span<charT> s) noexcept;
Effects: buf = s.
Initializes the input and output sequences according to mode.
Postconditions:
-
If ios_base::out is set in mode,pbase() == s.data() && epptr() == pbase() + s.size() is true;
in addition, if ios_base::ate is set in mode,pptr() == pbase() + s.size() is true,
otherwise pptr() == pbase() is true.
