Hello, Rust – Go vs. Rust: Concurrency and Race Conditions

One could also write the Go version using channels [1] and the Rust version in a more functional way [2], but overall the code is quite straightforward in both languages.

Only thing I don't like about the Rust version is, that the error message is still a bit cryptic:

``` Cannot borrow data mutably in a captured outer variable in an `Fn` closure. ```

But the important part is that Rust prevents a data race at compile time, which is nice.
