Swallowed many flies, and proved to myself I'm not yet fit enough again to cycle to work in the mornings, but I'm not as far from it as I thought I might be.
Still too tired from too short a ride though
Yeah I figure both `src` and `cargoSha256` would need to be overridden, and if the latter isn't easy to do, then the copy-pasta approach may be necessary. Ugh
I would be fetching from a branch in a repo, so fetchGit for sure; isn't there a cargo sha thing too though? I'm not sure, I should probably seek out the computed derivation and look I guess; but I don't know how :D
@grhmc So, Rust based packages in nixos - if I want to replace the *source* to the rustup package (ie. have it built from a test branch of my own) how do I express that in nix without just copying the package into my config and hacking at it? (I am still very junior nix-wise)
At some point I'll need to poke you to find out how to do an override for a rust package in nixpkgs so I can test this somewhat more like I used to under Debian.
I keep meaning to do something like have an "UNRELEASED" section and require PRs update that; but given I like to curate some news text too, that's still not ideal.
