Instructions not clear for: `modules/modules2.rs`
// TODO: Fix these use statements
use self::fruits::PEAR as ???
use self::veggies::CUCUMBER as ???
// ... snip
fn main() {
println!(
"favorite snacks: {} and {}",
delicious_snacks::fruit,
delicious_snacks::veggie
);
}
At first glance it seems as though the solution would simply be to replace the ???
with respective fruit
and veggie
;
However after much struggling and leaning on the rust discord community for assistance it was pointed out that the use
statement itself should also be changed to pub use
. This was not clear in the original problem, as the concept of making an import public is not one I'm accustomed to coming from other languages. The compiler doesn't event suggest this change, making it even more difficult to come to the correct answer without external assistance.
Yeah, good point, I'd imagine we can probably rewrite this exercise as a whole anyways, it's kind of clunky.
Including a link to the Rust Book documentation on re-exporting names in the hint might make this one clear enough. I also fumbled with this exercise a bit, but I knew I had read something in the Rust Book about this. I just couldn't remember where it was.
