Indeed, Rust + Cargo and Haskell + Stack are very similar in this regard. Both have great package managers, and both produce a shippable executable with only a few dependencies on system libraries. One notable difference is that Stack downloads the compiler, whereas for Rust, every version of the language comes with a compiler and a Cargo. This ensures that you can check out a year-old commit and still build your project with Stack (modulo breaking changes in Stack, which so far I have not encountered), whereas for Rust the compiler version is not pinned. |

Oh, you just need another layer of abstraction! Install rustup, and then (from memory, might be slightly wrong):
rustup will take care of getting hold of the right versions of cargo and rustc, and then use them to run the build. I admit that it's not as nice as having the build tool download the right version of everything, but it does work, and you could hide this inside a pretty small shell script or function if you wanted it to be neater.
