The legacy Deno CI workflow was removed to stop irrelevant lint and test failures across the repository. This change introduces a minimal, standard GitHub Actions workflow dedicated purely to validating Rust tooling.

Workflow Changes

• Remove Deno workflow: Deleted .github/workflows/deno.yml.
• Add Rust CI workflow: Added .github/workflows/rust.yml configured to:
  • Trigger on push and pull_request against main.
  • Enforce least-privilege token permissions (contents: read).
  • Provision the stable Rust toolchain and rustfmt component via dtolnay/rust-toolchain.
  • Execute cargo fmt --all --check, cargo check --verbose, and cargo test --verbose.

🔴 Validation fails without a Cargo project

Every run fails at cargo fmt --all --check because the repository has no Cargo manifest. Neither cargo check nor cargo test runs.

Learn more

The workflow runs at the repository root after checkout. This repository contains package.json and JavaScript source, but no Cargo.toml or Rust source. Cargo needs a manifest before it can format, check, or test a project, so every run stops at the first Cargo command.

Example: A pull request changes src/core/billing.js. Checkout succeeds, then cargo fmt --all --check reports that no Cargo.toml exists; the job fails without validating the change.

Recommended fix: Replace the Cargo steps with checks for the actual Node project, using the Node version specified by package.json and installing dependencies before running its checks. If Rust validation is intended for a future project, introduce its manifest and sources first.
