WalkthroughAdds a Nix flake for the project, declaring inputs (nixpkgs, flake-utils, rust-overlay) and outputs that define a per-system development shell. The shell includes Rust toolchain and common build tools, and runs a shellHook message on activation. No runtime or application code changes. Changes

1-8: LGTM! Clean flake structure.The description and inputs are well-configured. Using rust-overlay is a solid choice for Rust development environments.

🧩 Analysis chain
Verify flake.lock is committed.
Ensure that flake.lock is committed to the repository for reproducible builds. The lock file pins exact versions of all inputs.
Run this script to check if flake.lock exists and is tracked:
🏁 Script executed:
#!/bin/bash
# Check if flake.lock exists and is tracked by git

Add and commit flake.lock
Run nix flake lock to generate the lock file and commit it for reproducible builds.

In flake.nix around lines 1 to 36, the review notes that the repository is
missing the generated flake.lock file which is required for reproducible builds;
run `nix flake lock` at the repository root to generate flake.lock, add and
commit that new file to the repo (ensure your .gitignore does not exclude
flake.lock), and push the commit so CI and collaborators use the locked input
versions.

Remove redundant cargo from buildInputs.
The rust-bin.stable.latest.default toolchain from rust-overlay already includes cargo, making the explicit cargo entry on line 23 redundant.
Apply this diff:
buildInputs = with pkgs; [
rust
- cargo
openssl
pkg-config
sqlite
just
];📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

In flake.nix around lines 21 to 28, the buildInputs list redundantly includes
cargo even though the rust-bin.stable.latest.default toolchain from the
rust-overlay already provides cargo; remove the explicit cargo entry from the
buildInputs array (leave rust, openssl, pkg-config, sqlite, just) so the list no
longer contains cargo.

Please sign your commits and include the nix lock file. Otherwise this looks good to me.
