# Crate of the Week

This week's crate is [printpdf](https://crates.io/crates/printpdf), a pure Rust PDF-writing library that already has a lot of features (though I note a lot of
bool-taking methods). Thanks to [Felix Schütt](https://users.rust-lang.org/u/sharazam) for the suggestion!
This week's crate is [cargo-audit](https://crates.io/crates/cargo-audit), a cargo subcommand to look through a crates dependencies for known insecure versions. Thanks to [Danilo](https://users.rust-lang.org/u/dbrgn) for the suggestion!

[Submit your suggestions and votes for next week][submit_crate]!
