cargo-download

A cargo subcommand for downloading crates from crates.io

About

cargo-download can be used to download a gzipped archive of given crate, in the exact form that it was uploaded to crates.io.

This can be useful for a variety of things, such as:

checking in your dependencies in source control (if your team/organization follows this practice)
mirroring crates.io for reproducible CI/CD pipelines
security auditing of crates (esp. when a crate repository is missing)
reproducing a bug that only occurs in uploaded versions of your crate

cargo-download can be installed with cargo install:

$ cargo install cargo-download

This shall put the cargo-download executable in your Cargo binary directory (e.g. ~/.cargo/bin), which hopefully is in your $PATH.

To download the newest version of foo crate, do this:

$ cargo download foo >foo.gz

You can also use the standard Cargo.toml notation to specify a particular version:

$ cargo download foo==0.9 >foo-0.9.gz

For more detailed usage instructions, run cargo download --help.
