Is there a command to automatically add a crate to my Cargo.toml?

Question

I expected there to be something like: cargo install stopwatch but could not find it in the docs.

Finding the package version and manually adding the package to .toml:

[dependencies]
stopwatch="0.0.6"

Does not feel automated enough. :)

this is an [update](https://github.com/rust-lang/cargo/issues/5586) on that matter, in case someone is also wondering if the answer is outdated — ignacio, Dec 11 '21 at 10:59

No, there is no such thing built in to Cargo. There is only a cargo install subcommand which installs the binaries of a crate system-wide.

New third-party Cargo subcommands can be created, and cargo edit, does what you want.

These cargo subcommands can then be installed by cargo install, in a fun meta circle!

% cargo install cargo-edit

# Now `cargo add` is available
% cargo add mycrate

Ok, was just curious and had the feeling of missing something obvious. – Johan Larsson Oct 04 '15 at 14:07

As of Rust 1.62.0, you can use the following command to add dependencies, avoiding you to open the .toml file.

cargo add dependency@version
