Update Rust Derivation

Update the Rust derivation: $ARGUMENTS

Steps

1. •

   Read the derivation: Read the derivation file to understand its current structure, version, and hash fields.

2. •

   Update the version: Change the version attribute to the new version.

3. •

   Get the source hash:

   bash

   nix-prefetch-url --unpack "https://github.com/<owner>/<repo>/archive/refs/tags/v<version>.tar.gz"
   

   Then convert to SRI format:

   bash

   nix hash to-sri --type sha256 <hash>
   

4. •

   Update the source hash: Replace the hash attribute in fetchFromGitHub with the new SRI hash.

5. •

   Set cargoHash to placeholder: Temporarily set cargoHash = lib.fakeHash; to trigger nix to compute the correct hash.

6. •

   Build to get cargoHash:

   bash

   nix build --impure --expr 'let pkgs = import <nixpkgs> {}; in pkgs.callPackage ./<path-to-derivation> {}' 2>&1 | grep -A2 "got:"
   

   Extract the correct cargoHash from the error output.

7. •

   Update cargoHash: Replace lib.fakeHash with the actual cargoHash from the build output.

8. •

   Verify the build:

   bash

   nix build --impure --expr 'let pkgs = import <nixpkgs> {}; in pkgs.callPackage ./<path-to-derivation> {}'
   

   Ensure the build completes successfully.

9. •

   Summary: Report the version update (old -> new) and remind to run darwin-rebuild switch --flake . to apply changes.

Notes

• •The derivation must use rustPlatform.buildRustPackage with cargoHash
• •If using cargoLock instead of cargoHash, the process differs (fetch Cargo.lock from repo)
• •Some packages may have additional attributes that need updating (e.g., patches, buildInputs)
