The Sentinel concept specifies the relationship between an Iterator type and a Semiregular
Let s and i be values of type S and I, respectively, such that [i, s) denotes a range. Sentinel<S, I>
- i == s is well-defined.
- If bool(i != s) then
iis dereferenceable and[++i,s)
The domain of == can change over time. Given an iterator i and sentinel s such that
[
i
,
s
)
denotes a range and i != s,
[
i
,
s
)
is not required to continue to denote a range after incrementing any iterator equal to i (and so i == s
