cargo-supply-chain

Gather author, contributor and publisher data on crates in your dependency graph.

Use cases include:

  • Find people and groups worth supporting.
  • Identify risks in your dependency graph.
  • An analysis of all the contributors you implicitly trust by building their software. This might have both a sobering and humbling effect.

Usage

Run cargo install cargo-supply-chain to install this tool.

Once installed, simply navigate to your project and run cargo supply-chain followed by a subcommand, e.g. cargo supply-chain publishers

Subcommands

  • publishers - Lists all the people and teams that can publish updates to your dependencies on crates.io.
  • crates - Lists all the crates you depend on, with the list of publishers for each crate.
  • update - Downloads a daily database dump of crates.io (roughly 256Mb) to speed up publishers and crates subcommands. Data downloaded this way may be out of date by up to 48 hours. You can set the maximum allowed age using the --cache-max-age flag; if it's exceeded, live data will be fetched instead.
  • help - Displays detailed help for a specific command.

Filtering

Any arguments specified after -- will be passed to cargo metadata, for example:

cargo supply-chain crates -- --filter-platform=x86_64-unknown-linux-gnu

This will only include dependencies that are used when compiling for x86_64-unknown-linux-gnu and ignore crates that are not used on this platform (e.g. winapi, web-sys).

See cargo metadata --help for a list of flags it supports.
