Detector: Rust Clippy

Wraps cargo clippy for Rust code quality checks.

Property	Value
Name	rust-clippy
Tier	DETERMINISTIC
Languages	Rust
External tool	cargo clippy (Rust toolchain)
LLM required	No
Confidence	1.00

What it detects

Rust lint issues from Clippy — correctness, suspicious patterns, security concerns, style, and performance.

How it works

1. Checks for Rust project markers (Cargo.toml or .rs files)
2. Runs cargo clippy --message-format=json --quiet
3. Parses JSON Lines output, filtering for reason="compiler-message" entries
4. Deduplicates by file + line + message
5. Maps Clippy lint categories to Sentinel severity levels

High-severity categories

Clippy category	Description
clippy::correctness	Definite bugs
clippy::suspicious	Likely bugs
clippy::security	Security issues

Example finding

[RUST-CLIPPY] src/parser.rs:87 — clippy::correctness::infinite_loop
  This loop never terminates
  Severity: HIGH, Confidence: 1.00

Prerequisites

Clippy is included with the Rust toolchain:

rustup component add clippy

Known limitations

• Requires Rust toolchain installed
• 300-second timeout (Rust compilation can be slow)
• Skips target/ directory
