Rust's package manager

Usage: cargo [+toolchain] [OPTIONS] [COMMAND]

Options:
-V, --version Print version info and exit
--list List installed commands
--explain <CODE> Run `rustc --explain CODE`
-v, --verbose... Use verbose output (-vv very verbose/build.rs output)
-q, --quiet Do not print cargo log messages
--color <WHEN> Coloring: auto, always, never
-C <DIRECTORY> Change to DIRECTORY before doing anything
--frozen Require Cargo.lock and cache are up to date
--locked Require Cargo.lock is up to date
--offline Run without accessing the network
--config <KEY=VALUE> Override a configuration value
-Z <FLAG> Unstable (nightly-only) flags to Cargo, see 'cargo -Z help' for details
-h, --help Print help

Some common cargo commands are (see all commands with --list):
build, b Compile the current package
check, c Analyze the current package and report errors, but don't build object files
clean Remove the target directory
doc, d Build this package's and its dependencies' documentation
new Create a new cargo package
init Create a new cargo package in an existing directory
add Add dependencies to a manifest file
remove Remove dependencies from a manifest file
run, r Run a binary or example of the local package
test, t Run the tests
bench Run the benchmarks
update Update dependencies listed in Cargo.lock
search Search registry for crates
publish Package and upload this package to the registry
install Install a Rust binary. Default location is $HOME/.cargo/bin
uninstall Uninstall a Rust binary

See 'cargo help <command>' for more information on a specific command.

Add dependencies to a Cargo.toml manifest file

Usage: cargo add [OPTIONS] <DEP>[@<VERSION>] ...
cargo add [OPTIONS] --path <PATH> ...
cargo add [OPTIONS] --git <URL> ...

Arguments:
[DEP_ID]...
Reference to a package to add as a dependency

You can reference a package by:
- `<name>`, like `cargo add serde` (latest version will be used)
- `<name>@<version-req>`, like `cargo add serde@1` or `cargo add serde@=1.0.38`

Options:
--no-default-features
Disable the default features

--default-features
Re-enable the default features

-F, --features <FEATURES>
Space or comma separated list of features to activate

--optional
Mark the dependency as optional

The package name will be exposed as feature of your crate.

-v, --verbose...
Use verbose output (-vv very verbose/build.rs output)

--no-optional
Mark the dependency as required

The package will be removed from your features.

--color <WHEN>
Coloring: auto, always, never

--rename <NAME>
Rename the dependency

Example uses:
- Depending on multiple versions of a crate
- Depend on crates with the same name from different registries

--manifest-path <PATH>
Path to Cargo.toml

--frozen
Require Cargo.lock and cache are up to date

-p, --package [<SPEC>]
Package to modify

--locked
Require Cargo.lock is up to date

-q, --quiet
Do not print cargo log messages

--dry-run
Don't actually write the manifest

--offline
Run without accessing the network

--config <KEY=VALUE>
Override a configuration value

-Z <FLAG>
Unstable (nightly-only) flags to Cargo, see 'cargo -Z help' for details

-h, --help
Print help (see a summary with '-h')

Source:
--path <PATH>
Filesystem path to local crate to add

--git <URI>
Git repository location

Without any other information, cargo will use latest commit on the main branch.

--branch <BRANCH>
Git branch to download the crate from

--tag <TAG>
Git tag to download the crate from

--rev <REV>
Git reference to download the crate from

This is the catch all, handling hashes to named references in remote repositories.

--registry <NAME>
Package registry for this dependency

Section:
--dev
Add as development dependency

Dev-dependencies are not used when compiling a package for building, but are used for compiling tests, examples, and benchmarks.

These dependencies are not propagated to other packages which depend on this package.

--build
Add as build dependency

Build-dependencies are the only dependencies available for use by build scripts (`build.rs` files).

--target <TARGET>
Add as dependency to the given target platform

Run `cargo help add` for more detailed information.
