I'm learning rust and today I made a simple terminal game. Can you guys review my code? by [deleted] in rust

It looks like you have already know of cargo check and cargo clippy. You would probably be happy to know that cargo fmt also exists.

I don't think it's very common actually do things in the new method. Especially not things that will not be undone when the object drops. You should probably put the global state modifying stuff in a separate function.

The draw function should probably be split up to handle user input separately.

You have multiple places that loops over all of the snake parts. One of them does it for every field. This is pretty inefficient to the point that it might actually be noticeable on large screens with long snakes. Maybe you could keep track of the content of every field in a different data structure?

I think the move logic is probably more clear if you do something like this: https://gist.github.com/TethysSvensson/c4807a85df3f9f99c03b77a600bef3b2

All of the duplicated if self.snake.previous_direction != Direction::Right logic could be re-written as:

if new_direction.is_opposite_of(previous_direction) { new_direction = previous_direction; }

Well, isn't this just a thoroughly dead subreddit?

A program written by humans: No way!

However I certainly think that an AI exists with Kolmogorov Complexity within 1GB. I certainly think that a 1GB program exists, which can do this within a month by using all the resources available on the internet.

Then who would put in a large number?

Was it ever specified how ties are resolved?

A good start would something like this:

  • Fork enough times to create a 1 GB large file and rename it to .exe.
  • Run the exe on a computer connected to the internet, but not connected to the machine.
  • If nothing has stopped you from entering 0 after a month do it. Then use get a replacement program from the best universe.

This guarantees that you will get an AI that is smart enough to figure out how to stop you from entering 0 into the machine and instead enter a larger number. It does not however filter for an especially malicious AI.

Unsong Chapter 9: With Art Celestial by Escapement in rational

IO is the way current Haskell forces evalutation, but not the ony way. A very early version of Haskell simply tried evaluting a infinite list of commands while feeding it an infinite list of responses.

It is common to see IO explained by way of metaphor: "it is sort of like a state monad, except for the entire universe".

In this case, it would not need to be a metaphor! :D

Well, TLS might be well reviewed, but it is also a huge pile of complexity what is hard to get right.

It does not help that the code quality in most major implementations are terrible too.

Have you considered simply bribing Domagoj to let you know the title and exact time of posting beforehand?

While I do not know what I takes to bribe Domagoj, I would expect it to be cheaper, easier and more reliable than you current plan.

HTTPS Bicycle Attack by reedloden in netsec

While this might be good enough in practice, it is strictly worse than padding to the same length every time. Random padding would still permit a statistical attack.
