basic_spanstream::swap (C++23)

basic_spanstream::rdbuf (C++23)

Underlying buffer operations

basic_spanstream::span (C++23)

Non-member functions

swap(std::basic_spanstream) (C++23)

 

basic_spanstream& operator=( basic_spanstream&& other );	(1)	(since C++23)
basic_spanstream& operator=( const basic_spanstream& ) = delete;	(2)	(since C++23)

1) Move assigns the other to *this, effectively move-assigning both the std::basic_iostream base class subobject and the wrapped std::basic_spanbuf.

2) Copy assignment operator is deleted. basic_spanstream is not copy assignable.

Note that move assignment operator of the base class swaps all stream state variables (except for rdbuf()) between *this and other.

It is implementation-defined whether the std::basic_spanbuf wrapped in other still holds an underlying buffer after the move assignment.

Parameters

other

-

another stream to move from

Return value

*this

Exceptions

May throw implementation-defined exceptions.
