i.e. unions with non-POD members
We can't examine untagged unions, but we should be able to support
looking inside tagged unions at some point in the future.
We want to use the fully qualified name for scoped enums to keep the C++
compiler happy. When a parameter expects an enum value, we must supply
an enum value and not its underlying integer value.
Before:
isset_bitset<1, 0>
After:
isset_bitset<1, apache::thrift::detail::IssetBitsetOption::Unpacked>
This fixes linker errors in debug builds.
When building in debug mode (-DCMAKE_BUILD_TYPE=Debug), folly requires
the function "safe_assert_terminate" to be defined. To avoid building
and linking against folly, we define our own no-op version of this
function.
