#AdventOfCode #Da11 with #rust
yeah I skipped two days cause I couldn't get part 2 working. I'll get back to them later maybe.
Today is the first use of lifetimes, which seems necessary, but I'm not sure it really is.
Interesting bit: you can' use a HashSet as key of a Hash;ap (it does not implement Hash).
But this does not error out at the type alias declaration, but at the use site.
I find this odd.
Maybe I should use something else to declare the type?
