 rosssmyth | For an example of the caching, you can see what I did with Wild. Basically the assumption is "the Cargo.lock and flake.lock files do not change very often (compared to the rest of the souce)"
So there's a dedicated job that refreshes the cache when the lockfiles change
Then another job for running with the cached dependencies
And a cron job to periodically update the flake lockfile

| rosssmyth | You can use nightly and beta with buildRustPackage just as easily as the other options, so I wouldn't really say that's an advantage. It's even shown in the reference how to | 22:38:21 |
| rosssmyth | You just can't in Nixpkgs | 22:38:34 |
 neobrain | rosssmyth: How do you handle day-to-day development? Do you enter a nix shell or do you always nix run/build? If it's purely the former, I'm guessing the main benefit of the caching is for CI? | 22:39:26 |

| rosssmyth | The packages that allow it are rust-overlay and the other one I can't remember

| rosssmyth | Generally both. The caching in CI is pretty much always a win, then caching when I'm just doing day-to-day dev is also great cause I always like to verify that things build alright in the sandbox when I'm developing | 22:41:26 |

| rosssmyth | yeah | 22:42:30 |
| neobrain | I see, makes sense. Thanks for the explanation! | 22:43:29 |
