Rust Validator

Validate Rust code against configurable naming, documentation, function-size, panic, unwrap, unsafe, and project-policy rules. Results are policy findings, not compiler diagnostics.

Developer Input

Browser-based processing

Source code or data

pub fn load_user(id: u64) -> String {
    let value = find_user(id).unwrap();
    value
}

fn find_user(id: u64) -> Option<String> {
    Some(format!("user-{id}"))
}

Validation profile

Max function lines

lines

Require public documentation Forbid unwrap and expect Forbid unsafe and panic Auto-run while typing

How to use this developer tool

Paste Rust source code.
Choose a validation profile.
Set the maximum function length.
Run validation and review failed policy rules.

What this developer tool does

The validator applies profile-based project rules and produces passed, failed, and skipped counts with rule identifiers and suggested corrections.

Extract declarations → apply selected profile thresholds → evaluate naming and restricted patterns → calculate compliance score → generate policy report.

Ownership, borrowing, lifetimes, type inference, and trait resolution require cargo check or rustc and are not validated here.

Example

The page loads a working Rust Validator 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 enforce Rust coding rules online?

Choose a validation profile and run the validator to check naming, documentation, size, and restricted-pattern policies.

What is the difference between Rust Checker and Rust Validator?

A checker looks for structural or risky patterns, while this validator focuses on configurable team and project policies.

Can I validate Rust ownership and lifetimes here?

No. Those require compiler-level analysis with cargo check or rustc.

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.
