JSON support is provided by serde_json, which is owned by dtolnay, a longtime member of the Rust standard library team. Regex is provided by the regex crate, owned by burntsushi, a longtime member of the Rust standard library team. Directory walking is provided by walkdir, also owned by burntsushi. RNG is provided by the rand crate, owned by the rust-random organization, also full of longtime Rust contributors. CLI argument parsing is provided by the clap crate, owned by epage, the lead developer of Cargo. These aren't randos, these are all de-facto first party libraries. You can trust these developers as much as you trust any random owner of any random Debian package.
