Rust doesn't allow specialization and likely never will because it's unsound https://www.reddit.com/r/rust/comments/1p346th/specializatio... has a couple of nice comments about it.

But yes it's basically

template <typename T, size_t N> class Example { vector<T> generic; };

template<> class Example<int32_t, 32> { int bitpackinhere; }
