It really depends on what you think are the features of Haskell that typify its &quot;family&quot;. If you think it&#x27;s typified by things like type inference, sum types, and typeclasses, then Rust will feel very Haskell-y, but if you think it&#x27;s typified by higher kinded types, laziness, and functional purity, then it won&#x27;t feel very Haskell-y at all.<p>Personally, I think Haskell and C++ are the two biggest influences I feel when using Rust: it has a lot of Haskell&#x27;s philosophy around data types and polymorphism, and a lot of C++&#x27;s philosophy around the life cycle of resources, and the cost of abstractions.
