explicit basic_spanbuf(std::span<charT> s, ios_base::openmode which = ios_base::in | ios_base::out);
Effects: Initializes the base class with basic_streambuf() ([streambuf.cons]), and mode with which.
Initializes the internal pointers as if calling span(s).
basic_spanbuf(basic_spanbuf&& rhs);
Effects: Initializes the base class with std::move(rhs) andmode with std::move(rhs.mode) andbuf with std::move(rhs.buf).
The sequence pointers in *this (eback(), gptr(), egptr(),pbase(), pptr(), epptr()) obtain the values which rhs had.
It isimplementation-defined whether rhs.buf.empty() returns true after the move.
Postconditions: Let rhs_p refer to the state of rhs just prior to this construction.
span().data() == rhs_p.span().data()
span().size() == rhs_p.span().size()
eback() == rhs_p.eback()
gptr() == rhs_p.gptr()
egptr() == rhs_p.egptr()
pbase() == rhs_p.pbase()
pptr() == rhs_p.pptr()
epptr() == rhs_p.epptr()
getloc() == rhs_p.getloc()
