template< container-compatible-range<CharT> R > constexpr iterator insert_range( const_iterator pos, R&& rg );		(since C++23)

Inserts characters from the range rg before the element (if any) pointed by pos.

Equivalent to

return insert(pos - begin(),
    std::basic_string(
        std::from_range,
        std​::​forward<R>(rg),
        get_allocator())
);

If pos is not a valid iterator on *this, the behavior is undefined.

Parameters

pos	-	iterator before which the characters will be inserted
rg	-	a

Return value

An iterator which refers to the first inserted character, or pos if no characters were inserted because rg was empty.

Complexity

Linear in size of rg.

Exceptions

If std::allocator_traits<Allocator>::allocate throws an exception, it is rethrown.

If the operation would result in size() > max_size(), throws std::length_error.

If an exception is thrown for any reason, this function has no effect (strong exception safety guarantee).
