Rust Inspector

Inspect Rust code for maintainability, unsafe density, unwrap and panic use, clone and allocation patterns, function size, nesting, and async-risk heuristics.

Developer Input

Browser-based processing

Source code or data

pub async fn load_all(ids: Vec<u64>) -> Vec<String> {
    let mut output = Vec::new();
    for id in ids {
        let value = fetch(id).await.unwrap().clone();
        output.push(value.to_string());
    }
    output
}

How to use this developer tool

Paste Rust source code.
Choose the inspection focus.
Set the function-length warning threshold.
Inspect and review the highest-priority findings first.

What this developer tool does

The inspector produces static and heuristic findings with maintainability, safety, complexity, and error-handling scores. Compiler-dependent conclusions are clearly marked.

Extract function regions → count complexity and risk tokens → detect loop and async contexts → classify static versus heuristic findings → calculate scores.

Ownership, borrow, and lifetime findings are heuristic. Run cargo check and cargo clippy for compiler-level verification.

Example

The page loads a working Rust Inspector example. Run the tool to compare the sample input with the generated output and status summary.

Tips for better output

Start with valid, isolated code or data.
Review heuristic and inferred results manually.
Use the official compiler, formatter, linter, or IDE before production use.

FAQ

How can I measure Rust code complexity online?

Run a balanced or complexity-focused inspection to estimate function size, branches, nesting, and risk density.

How do I detect excessive clone or unwrap usage in Rust?

The inspector counts these calls and flags higher-risk contexts such as loops and reusable functions.

Can this tool detect borrow checker errors?

No. Borrow and lifetime observations are heuristic and require cargo check for verification.

Can this browser tool replace the official compiler or IDE inspection?

No. It performs browser-based formatting, conversion, structural parsing, or heuristic analysis. Always verify production code with the official toolchain.

Does this tool upload my source code?

No processing is implemented by the page itself in your browser. Review your hosting and analytics configuration separately if you add external services.
