Constructs a new basic_ospanstream
.
1) Uses the storage referenced by s as initial underlying buffer of the wrapped std::basic_spanbuf device. The wrapped std::basic_spanbuf object is constructed as basic_spanbuf<Char, Traits>(s, mode | std::ios_base::out).
2) Move constructor. Move constructs the std::basic_ostream base subobject and the wrapped std::basic_spanbuf from those of rhs, and then calls set_rdbuf with the address of the wrapped std::basic_spanbuf in *this to install it.
3) Copy constructor is deleted.
