NAME

       std::default_sentinel_t

SYNOPSIS

Detailed Description

       A sentinel type that can be used to check for the end of a range.

       For some iterator types the past-the-end sentinel value is independent of the underlying
       sequence, and a default sentinel can be used with them. For example, a
       std::counted_iterator keeps a count of how many elements remain, and so checking for the
       past-the-end value only requires checking if that count has reached zero. A past-the-end
       std::istream_iterator is equal to the default-constructed value, which can be easily
       checked.

       Comparing iterators of these types to std::default_sentinel is a convenient way to check
       if the end has been reached.
