Compares a basic_const_iterator with another value.
The != operator is synthesized from operator==.
I satisfies /*different-from*/<basic_const_iterator> if std::same_as<I, basic_const_iterator<Iter>> is false.
Parameters
| s
|
-
|
a sentinel for Iter
|
| y
|
-
|
a value to compare with
|
Return value
1) base() == s
2) base() < y.base()
3) base() > y.base()
4) base() <= y.base()
5) base() >= y.base()
6) base() <=> y.base()
7) base() < y
8) base() > y
9) base() <= y
10) base() >= y
11) base() <=> y
Notes
Overload (1) can be used to compare two basic_const_iterator<Iter> values if Iter models sentinel_for<Iter>.
