rust-rustrover-cargo Cursor ruleA

rust-rustrover-cargo from moeru-ai/auv is a Cursor rule: instructions the Cursor agent follows in that repo.

Install it, pinned

mdr add moeru-ai/auv/.cursor/rules/rust-rustrover-cargo.mdc@git:20260628.94103e1

Pins git:20260628.94103e1 in mdr.lock. Pin the fingerprint instead.

Rust edits use RustRover MCP for structure and Cargo for validation.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Rust: RustRover MCP + Cargo (AUV)

When this rule applies, treat RustRover MCP as the **required** structure layer and terminal Cargo as the **required** validation authority.

## Before editing Rust

1. Confirm RustRover MCP (`user-rustrover`) is available; read tool schemas before calling.
2. Locate symbols with MCP first:
   - `search_symbol` → `get_symbol_info`
   - `analyze_calls` when changing public APIs, traits, or call sites
   - `search_file` for crate/test/fixture paths
3. Do **not** start with plain `grep`/`rg` for structural Rust work (types, traits, methods, callers).
4. Plain text search is still OK for: docs, fixtures, JSON artifacts, logs, comments, literal CLI strings — after semantic lookup fails or target is non-code.

## While editing

- Prefer `rename_refactoring` for symbol renames across the workspace.
- Optional: `reformat_file` on touched files (helper only; not proof of correctness).
- Optional: `get_file_problems` / `build_project` for fast IDE feedback.

## After editing Rust (required)

Run from repo root before claiming done:

```sh
cargo fmt --check
cargo check
cargo test   # or a narrow filter when the slice is localized
git diff --check
```
…

How to install

The exact contents, by fingerprint

mdr add moeru-ai/auv/.cursor/rules/rust-rustrover-cargo.mdc@sha256:751d2db58821d0a1

The line at the top of this page pins the label git:20260628.94103e1, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
