template <class Pair, class = std::true_type>struct OffsetOf
Defined at line 273 of file ../../third_party/abseil-cpp/absl/container/internal/container_memory.h
If Pair is a standard-layout type, OffsetOf
<Pair
>::kFirst and
OffsetOf
<Pair
>::kSecond are equivalent to offsetof(Pair, first) and
offsetof(Pair, second) respectively. Otherwise they are -1.
The purpose of OffsetOf is to avoid calling offsetof() on non-standard-layout
type, which is non-portable.
