std::ranges::repeat_view::iterator::iterator

/iterator/()=default;	(1)	(since C++23)
constexprexplicit/iterator/ (const W* value,/index-type/ b=/index-type/());	(2)	(since C++23) (exposition only*)

Constructs an iterator. Overload(2) is called bybegin() andend() ofranges::repeat_view.

1) Initializesvalue_ withnullptr and value-initializescurrent_ .

2) Initializesvalue_ withvalue andcurrent_ withb.

IfBound is notstd::unreachable_sentinel_t andb is negative, the behavior is undefined.

std::ranges::repeat_view::iterator::operator*

constexprconst W& operator*()constnoexcept;		(since C++23)

Returns*value_.

std::ranges::repeat_view::iterator::operator[]

constexprconst W& operator[]( difference_type n)constnoexcept;		(since C++23)

Returns*(*this+ n).

std::ranges::repeat_view::iterator::operator++

constexpr/iterator/& operator++();	(1)	(since C++23)
constexprvoid operator++(int);	(2)	(since C++23)

1) Equivalent to++current_ ;return*this;.

2) Equivalent toauto tmp=*this;++*this;return tmp;.

std::ranges::repeat_view::iterator::operator--

constexpr/iterator/& operator--();	(1)	(since C++23)
constexpr/iterator/ operator--(int);	(2)	(since C++23)

1) Equivalent to--current_ ;return*this;.

IfBound is notstd::unreachable_sentinel_t andcurrent_ is non-positive, the behavior is undefined.

2) Equivalent toauto tmp=*this;--*this;return tmp;.

std::ranges::repeat_view::iterator::operator+=

constexpr/iterator/& operator+=( difference_type n);		(since C++23)

Equivalent tocurrent_ += n;return*this;.

IfBound is notstd::unreachable_sentinel_t andcurrent_ + n is negative, the behavior is undefined.

std::ranges::repeat_view::iterator::operator-=

constexpr/iterator/& operator-=( difference_type n);		(since C++23)

Equivalent tocurrent_ -= n;return*this;.

IfBound is notstd::unreachable_sentinel_t andcurrent_ - n is negative, the behavior is undefined.

[edit]Non-member functions

operator==, <=>(std::ranges::repeat_view::iterator)

friendconstexprbool operator== (const/iterator/& x,const/iterator/& y);	(1)	(since C++23)
friendconstexprauto operator<=> (const/iterator/& x,const/iterator/& y);	(2)	(since C++23)

1) Returnsx.current_ == y.current_.

2) Returnsx.current_ <=> y.current_.

The!= operator issynthesized fromoperator==.

These functions are not visible to ordinaryunqualified orqualified lookup, and can only be found byargument-dependent lookup wheniterator is an associated class of the arguments.

operator+(std::ranges::repeat_view::iterator)

friendconstexpr/iterator/ operator+ (/iterator/ i, difference_type n);	(1)	(since C++23)
friendconstexpr/iterator/ operator+ ( difference_type n,/iterator/ i);	(2)	(since C++23)

Equivalent toi+= n;return i;.

These functions are not visible to ordinaryunqualified orqualified lookup, and can only be found byargument-dependent lookup wheniterator is an associated class of the arguments.

operator-(std::ranges::repeat_view::iterator)

friendconstexpr/iterator/ operator- (/iterator/ i, difference_type n);	(1)	(since C++23)
friendconstexpr difference_type operator- (const/iterator/& x,const/iterator/& y);	(2)	(since C++23)

1) Equivalent toi-= n;return i;.

2) Returnsstatic_cast<difference_type>(x.current_ )-
static_cast<difference_type>(y.current_ ).

These functions are not visible to ordinaryunqualified orqualified lookup, and can only be found byargument-dependent lookup wheniterator is an associated class of the arguments.
