Check Rust code for structural issues, unsafe blocks, unwrap and panic usage, incomplete macros, and heuristic borrow risks. Processing runs locally in your browser and produces copy-ready output with practical review notes.
Check Rust code for structural issues, unsafe blocks, unwrap and panic usage, incomplete macros, and heuristic borrow risks.
Browser-based analysis cannot replace the official compiler, formatter, linter, module resolver, or project test suite. Verify production code with the appropriate Go or Rust toolchain.
Input:
fn main() {
let value: Option<i32> = None;
println!("{}", value.unwrap());
}Output: Load the included example and click Check Rust to produce a complete, testable result in the output card.Paste Rust code and run the checker for delimiter, declaration, macro, unsafe, unwrap, and panic-pattern analysis. Use cargo check for compiler-level verification.
The checker scans code outside strings and comments and reports unwrap(), expect(), panic!, todo!, and unimplemented! calls with line numbers.
Only partially. Ownership, borrowing, and lifetime findings are heuristic because definitive results require rustc's borrow checker.
Enable unsafe detection. Each unsafe block and unsafe function declaration is listed as a manual review item rather than an automatic error.
Cargo check resolves modules, crates, types, traits, lifetimes, and ownership rules that browser-only static analysis cannot reproduce.
| Module | Purpose |
|---|---|
| Input normalization | Normalizes line endings and safe whitespace. |
| Static processing | Runs the selected analysis, transformation, or generation logic. |
| Result metrics | Reports characters, lines, bytes, status, and processing time. |
