std::basic_ospanstream<CharT,Traits>::basic_ospanstream
explicit basic_ospanstream( std::span<CharT> s, std::ios_base::openmode mode =
std::ios_base::out ); |
(1) | (since C++23) |
basic_ospanstream( basic_ospanstream&& rhs ); |
(2) | (since C++23) |
basic_ospanstream( const basic_ospanstream& ) = delete; |
(3) | (since C++23) |
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.
basic_ospanstream is not copyable.
Parameters
| s | - | std::span referencing the storage to be use as initial underlying buffer of stream |
||||||||||||||
| mode | - | specifies stream open mode. Following constants and bit-wise OR between them may be used:
|
||||||||||||||
| other | - | another basic_ospanstream to be moved from |
Exceptions
May throw implementation-defined exceptions.
