Yesterday I talked about an issue I had updating a Rust project. The time between when that project was working for me and when it was not was only a few months.
But I have one other Rust project I haven't touched in a while. This little game.
In it, you play as a Pong paddle catching or dodging bullets from an alien. It was a fun project at the time and a good exercise with Rust.
It also does not compile today.

error: could not compile `winit` (lib) due to 7 previous errorsA lot of people suggested locking to an older version of the Rust toolchain. So I tried to set my laptop to have whatever the Rust compiler was the last time I made a commit on that project.
➜ alien_game git:(master) ✗ rustup toolchain install stable-2020-03-25
info: syncing channel updates for 'stable-2020-03-25-aarch64-apple-darwin'
error: no release found for 'stable-2020-03-25'Oh, yeah. ARM Macs weren't a thing in 2020.
I no longer have the laptop I used to write this code.
I can't find a list of available toolchains online and trying every date is tiresome - maybe I'll script it if all else fails - but there are only two dependencies.
[dependencies]
ggez = "0.5"
rand = "0.7.3"What if I just lock newer versions of winit and cocoa?
