OPTIONS

   Special Options
       -V, --version
           Print version info and exit. If used with --verbose, prints extra information.

       --list
           List all installed Cargo subcommands. If used with --verbose, prints extra
           information.

       --explain CODE
           Run rustc --explain CODE which will print out a detailed explanation of an error
           message (for example, E0004).

   Display Options
       -v, --verbose
           Use verbose output. May be specified twice for "very verbose" output which includes
           extra output such as dependency warnings and build script output. May also be
           specified with the term.verbose config value
           <https://doc.rust-lang.org/cargo/reference/config.html>.

       -q, --quiet
           No output printed to stdout.

       --color WHEN
           Control when colored output is used. Valid values:

           ·   auto (default): Automatically detect if color support is available on the
               terminal.

           ·   always: Always display colors.

           ·   never: Never display colors.

           May also be specified with the term.color config value
           <https://doc.rust-lang.org/cargo/reference/config.html>.

   Manifest Options
       --frozen, --locked
           Either of these flags requires that the Cargo.lock file is up-to-date. If the lock
           file is missing, or it needs to be updated, Cargo will exit with an error. The
           --frozen flag also prevents Cargo from attempting to access the network to determine
           if it is out-of-date.

           These may be used in environments where you want to assert that the Cargo.lock file is
           up-to-date (such as a CI build) or want to avoid network access.

       --offline
           Prevents Cargo from accessing the network for any reason. Without this flag, Cargo
           will stop with an error if it needs to access the network and the network is not
           available. With this flag, Cargo will attempt to proceed without the network if
           possible.

           Beware that this may result in different dependency resolution than online mode. Cargo
           will restrict itself to crates that are downloaded locally, even if there might be a
           newer version as indicated in the local copy of the index. See the cargo-fetch(1)
           command to download dependencies before going offline.

           May also be specified with the net.offline config value
           <https://doc.rust-lang.org/cargo/reference/config.html>.

   Common Options
       -h, --help
           Prints help information.

       -Z FLAG...
           Unstable (nightly-only) flags to Cargo. Run cargo -Z help for details.

ENVIRONMENT

       See the reference <https://doc.rust-lang.org/cargo/reference/environment-variables.html>
       for details on environment variables that Cargo reads.

EXIT STATUS

       0
           Cargo succeeded.

       101
           Cargo failed to complete.

FILES

       ~/.cargo/
           Default location for Cargo’s "home" directory where it stores various files. The
           location can be changed with the CARGO_HOME environment variable.

       $CARGO_HOME/bin/
           Binaries installed by cargo-install(1) will be located here. If using rustup,
           executables distributed with Rust are also located here.

       $CARGO_HOME/config
           The global configuration file. See the reference
           <https://doc.rust-lang.org/cargo/reference/config.html> for more information about
           configuration files.

       .cargo/config
           Cargo automatically searches for a file named .cargo/config in the current directory,
           and all parent directories. These configuration files will be merged with the global
           configuration file.

       $CARGO_HOME/credentials
           Private authentication information for logging in to a registry.

       $CARGO_HOME/registry/
           This directory contains cached downloads of the registry index and any downloaded
           dependencies.

       $CARGO_HOME/git/
           This directory contains cached downloads of git dependencies.

       Please note that the internal structure of the $CARGO_HOME directory is not stable yet and
       may be subject to change.

EXAMPLES

        1. Build a local package and all of its dependencies:

               cargo build

        2. Build a package with optimizations:

               cargo build --release

        3. Run tests for a cross-compiled target:

               cargo test --target i686-unknown-linux-gnu

        4. Create a new package that builds an executable:

               cargo new foobar

        5. Create a package in the current directory:

               mkdir foo && cd foo
               cargo init .

        6. Learn about a command’s options and usage:

               cargo help clean
