-🎄- 2021 Day 6 Solutions -🎄-
Very similar to mine, I used .rotate(1) on my ages array then added the element at the end to the element at index 6. https://github.com/MichaelCG8/aoc2021/blob/main/src/bin/06.rs

Code review AoC Day 4
Also, instead of summing the remaining values at the end I summed them all at the start then subtracted them as they were checked off, meaning that i didn't need to store a Boolean for each entry recording whether it remained. https://github.com/MichaelCG8/aoc2021/blob/main/src/bin/04.rs

Day 6 Proof of Correctness
Note also that you can solve this without a complexity dependency on n. Most solutions I have seen, including mine run in time O(tD), where t is the maximum value of a timer, and D the number of generation, requiring O(t) memory. (This is assuming we can do the required arithmetic operations in constant time, and each numbers require a fixed around of memory storage; if the number of fish gets huge, throw in an additional log n in the complexities, where n is the number of fish on the final day).

In my Perl solution of today (I assume, you mean 2021, Day 4), I read stuff in paragraph mode ($/ = "") which makes Perl split input on 2 or more newlines.
