Jan, 2023 The concurrent hashmap classes internally represent entries as a uintptr_t. But the user-facing classes get templated on types that could be any POD-like type that can fit in that size. To convert from a uintptr_t to such a type T, we need to first convert to a properly-sized unsigned type using static_cast, and then use a union to convert to T.
