cargo-machete VS cargo-deny

cargo-machete is a Cargo plugin for cutting out unused dependencies from your project. To install it, you can use cargo install cargo-machete then use cargo machete in a Rust project directory.

cargo machete can remove unused imports.

Tip: You can check the licenses of all your dependencies (recursively) using cargo-deny: https://github.com/EmbarkStudios/cargo-deny

cargo-deny

cargo-deny can help block specified versions of a crate and even has some advisory features that can probably used to block crate with reported vulnerabilities

cargo deny for fetching crates only from trusted sources, blacklisting crates, etc.

Use cargo audit or cargo deny to check the crates in your Cargo.lock to ensure they don't contain any vulnerabilities.

> Explain the crate scanner thing?

I assume a reference to tools that help manage potential issues around dependencies, e.g.:

* https://github.com/rustsec/rustsec/tree/main/cargo-audit

* https://github.com/EmbarkStudios/cargo-deny

"[cargo-audit] Audit Cargo.lock files for crates with security vulnerabilities reported to the RustSec Advisory Database."

"cargo-deny is a cargo plugin that lets you lint your project's dependency graph to ensure all your dependencies conform to your expectations and requirements." e.g. license, security advisories, source.

cargo-deny does license and security advisory checking, and cargo-geiger does unsafe checking.

cargo-deny

OpenSSL has been banned in our project for a variety of reasons via cargo-deny for around a year and half, it was actually one of the reasons we created it in the first place.
