linter-rust

C2Rust helps you migrate C99-compliant code to Rust. The translator (or transpiler) produces unsafe Rust code that closely mirrors the input C code.

Audit Cargo.lock for crates with security vulnerabilities reported to the RustSec Advisory Database.

Find out what takes most of the space in your executable. supports ELF (Linux, BSD), Mach-O (macOS) and PE (Windows) binaries.

cargo-breaking compares a crate's public API between two different branches, shows what changed, and suggests the next version according to semver.

Whole program static stack analysis The tool produces the full call graph of a program as a dot file.

A cargo plugin for linting your dependencies. It can be used either as a command line too, a Rust crate, or a Github action for CI. It checks for valid license information, duplicate crates, security vulnerabilities, and more.

Cargo subcommand to show result of macro expansion and #[derive] expansion applied to the current crate. This is a wrapper around a more verbose compiler command.

A cargo plugin for analysing the usage of unsafe Rust code Provides statistical output to aid security auditing

Inspect Rust code without syntactic sugar to see what the compiler does behind the curtains.

Scan your Rust crate releases for semver violations. It can be used either directly via the CLI, as a GitHub Action in CI, or via release managers like release-plz. It found semver violations in more than 1 in 6 of the top 1000 most-downloaded crates on crates.io.

cargo subcommand showing the assembly, LLVM-IR and MIR generated for Rust code

Checks all your documentation for spelling and grammar mistakes with hunspell (ready) and languagetool (preview)

Find unused dependencies in Cargo.toml. It either prints out a "unused crates" line listing the crates, or it prints out a line saying that no crates were unused.

Find potential unused enabled feature flags and prune them. You can generate a simple HTML report from the json to make it easier to inspect results. It removes a feature of a dependency and then compiles the project to see if it still compiles. If it does, the feature flag can possibly be removed, but it can be a false-positive.

A code linter to catch common mistakes and improve your Rust code.

Web application (WASM) to render a diff between Rust crate versions.

A tool for running Rust lints from dynamic libraries. Dylint makes it easy for developers to maintain their own personal lint collections.

A tool for formally verifying Rust programs by transpiling them into definitions in the Lean theorem prover.

Adds warnings or errors to your crate when using a numerically unstable floating point expression.

The Kani Rust Verifier is a bit-precise model checker for Rust. Kani is particularly useful for verifying unsafe code blocks in Rust, where the "unsafe superpowers" are unchecked by the compiler. Kani verifies:

• Memory safety (e.g., null pointer dereferences)
• User-specified assertions (i.e., assert!(...))
• The absence of panics (e.g., unwrap() on None values)
• The absence of some types of unexpected behavior (e.g., arithmetic overflows)

Statically detects Rust deadlocks bugs. It currently detects two common kinds of deadlock bugs: doublelock and locks in conflicting order. It will print bugs in JSON format together with the source code location and an explanation of each bug.

And abstract interpreter operating on Rust's mid-level intermediate language, and providing warnings based on taint analysis.

Provides a convenient macro that allows you to generate type wrappers that promise to always uphold arbitrary invariants that you specified.

A static verifier for Rust, based on the Viper verification infrastructure. By default Prusti verifies absence of panics by proving that statements such as unreachable!() and panic!() are unreachable.

Rust Memory Safety & Undefined Behavior Detection. It is capable of analyzing single Rust packages as well as all the packages on crates.io.

Audit Rust binaries for known bugs or security vulnerabilities. This works by embedding data about the dependency tree (Cargo.lock) in JSON format into a dedicated linker section of the compiled executable.

Read and apply the suggestions made by rustc (and third-party lints, like those offered by clippy).

RustViz is a tool that generates visualizations from simple Rust programs to assist users in better understanding the Rust Lifetime and Borrowing mechanism. It generates SVG files with graphical indicators that integrate with mdbook to render visualizations of data-flow in Rust programs.

Show unused code from multi-crate Rust projects

Execute Rust code carefully, with extra checking along the way. It builds the standard library with debug assertions. Here are some of the checks this enables:

• get_unchecked in slices performs bounds checks * copy, copy_nonoverlapping, and write_bytes check that pointers are aligned and non-null and (if applicable) non-overlapping {NonNull,NonZero*,...}::new_unchecked check that the value is valid * plenty of internal consistency checks in the collection types * mem::zeroed and the deprecated mem::uninitialized panic if the type does not allow that kind of initialization

A command-line benchmarking tool It features statistical analysis across multiple runs, support for arbitrary shell commands, constant feedback about the benchmark progress and current estimates, warmup runs, a simple and expressive syntax, and more.

Concurrency permutation testing tool for Rust. It runs a test many times, permuting the possible concurrent executions of that test.

An interpreter for Rust's mid-level intermediate representation, which can detect certain classes of undefined behavior like out-of-bounds memory accesses and use-after-free.

Instrumentation profiler for Rust.

How-to sanitize your Rust code with built-in Rust dynamic analyzers

provides a visualization for quickly identifying common bottlenecks in running, asynchronous, and concurrent applications.

ast-grep is a powerful tool designed for managing code at scale using Abstract Syntax Trees (AST). Think of it as a hybrid of grep, eslint, and codemod, with the ability to search, lint, and rewrite code based on its structure rather than plain text. It supports multiple languages and is designed to be extensible, allowing you to register custom languages.

A linter and formatter to help you to improve copywriting, correct spaces, words, punctuations between CJK (Chinese, Japanese, Korean).

Statically generates a call graph image and displays it on screen.

Semi-automatic translation from C to Rust. Could reveal bugs in the original implementation by showing Rust compiler warnings and errors. Superseded by C2Rust.

Multi-language Static Application Security Testing (SAST) platform that detects critical vulnerabilities, including hardcoded secrets, weak cryptography, backdoors, SQL injections, insecure configurations, etc.

Keploy is an open-source testing platform that helps developers automate and streamline their testing process. It provides API, and integration testing agents, generating tests, mocks/stubs for APIs that actually work. Additionally, Keploy offers an AI-powered Unit Testing Agent that generates stable, useful unit tests directly in your GitHub PRs and in VSCode, helping catch errors and improve code quality.

Lizard is an extensible Cyclomatic Complexity Analyzer for many programming languages including C/C++ (doesn't require all the header files or Java imports). It also does copy-paste detection (code clone detection/code duplicate detection) and many other forms of static code analysis. Counts lines of code without comments, CCN (cyclomatic complexity number), token count of functions, parameter count of functions.
