meta::sentinel_t

Defined in header <mgs/meta/sentinel_t.hpp>.

template <typename T>
using sentinel_t = /* see below */;

Pre-C++20 implementation of std::ranges::sentinel_t.

---

Differences with the C++20 version

• The implementation does not rely on std::ranges::end, but on the usual customization point idiom, i.e. using std::end; end(/* ... */);.
