Shell example should be added to the description.

How about some random tests?

This need random tests

OK - You guys are the Rust experts. Not me; If you tried what I asked for but it cannot be done then that is enough. Thanks for trying. The translation is approved.

By default, if a test passes, Rust’s test library captures anything printed to standard output.
Rust Book

Looks like the solution is flags passed to cargo (e.g. $ cargo test -- --nocapture), but I don't think that's possible...

I'll do some research on that with other Rust Katas and see how to do that.

FYI: The output for the random tests only appears if the solution is wrong

Please make it appear always (same as all other translation of this Kata).

• I returned 1 by default in the setup to avoid the compiler error about mismatched types
• I switched to u32 (not that it really matters with such small integers)
• I switched to Vectors instead of slices (since in the random tests, we're already creating Vectors)

I favored fold on the Iterator trait (this is the largest change based on something I liked in the JavaScript solutions)

FYI: The output for the random tests only appears if the solution is wrong
