| thomasjm | hi all, does anyone know when Rust >= 1.85 will be available in Nixpkgs? i'd like to package something that uses edition2024... | 02:50:50 |
 emily | a week or two | 03:45:46 |
 Alyssa Ross | You can already package whatever it is on staging-next | 08:36:37 |

buildRustPackage has finalAttrs now. I'm happy. To clarify, currently buildRustPackage's attr construction function doesn't actually utilize the finalAttrs part yet, so e.g. if you override cargoHash it wont actually get changed inside the FOD.
So ATM it's just the plain old logic + support for usage of the finalAttrs pattern by consumers (which is still great) | 19:19:18 |

| Andrew | I have this:
home-manager.users.${user} = {
home.packages = with pkgs; [
(fenix.stable.withComponents [
"cargo"
"clippy"
"rust-src"
"rustc"
"rustfmt"
])
fenix.targets.wasm32-wasip1.latest.rust-std
fenix.targets.wasm32-wasip2.latest.rust-std
fenix.targets.wasm32-unknown-unknown.latest.rust-std
rust-analyzer-nightly
cargo-expand
pkg-config
];
But cargo build still doesn't see any of the wasm targets installed. I used the overlay usage approach.

 ghpzin | You probably need to do it differently with fenix, I would try with combine:

(ignoring how it would be better to do it in shell and not "globally" in your HM config) | 15:58:10 |
