       cargo-publish - Upload a package to the registry

       cargo publish [options]

       This command will create a distributable, compressed .crate file with
       the source code of the package in the current directory and upload it
       to a registry. The default registry is <https://crates.io>. This
       performs the following steps:

        1. Performs a few checks, including:

           o  Checks the package.publish key in the manifest for restrictions
               on which registries you are allowed to publish to.

        2. Create a .crate file by following the steps in cargo-package(1).

        3. Upload the crate to the registry. Note that the server will perform
           additional checks on the crate.

       This command requires you to be authenticated with either the --token
       option or using cargo-login(1).

       See the reference
       <https://doc.rust-lang.org/cargo/reference/publishing.html> for more
       details about packaging and publishing.

   Publish Options
           Perform all checks without uploading.

       --token token
           API token to use when authenticating. This overrides the token
           stored in the credentials file (which is created by

           Cargo config
           <https://doc.rust-lang.org/cargo/reference/config.html> environment
           variables can be used to override the tokens stored in the
           credentials file. The token for crates.io may be specified with the
           CARGO_REGISTRY_TOKEN environment variable. Tokens for other
           registries may be specified with environment variables of the form
           CARGO_REGISTRIES_NAME_TOKEN where NAME is the name of the registry
           in all capital letters.

           Don't verify the contents by building them.

           Allow working directories with uncommitted VCS changes to be

       --index index
           The URL of the registry index to use.

       --registry registry
           Name of the registry to publish to. Registry names are defined in
           Cargo config files
           <https://doc.rust-lang.org/cargo/reference/config.html>. If not
           specified, and there is a package.publish
           field in Cargo.toml with a single registry, then it will publish to
           that registry. Otherwise it will use the default registry, which is
           defined by the registry.default
           config key which defaults to crates-io.

   Compilation Options
       --target triple
           Publish for the given architecture. The default is the host
           architecture. The general format of the triple is
           <arch><sub>-<vendor>-<sys>-<abi>. Run rustc --print target-list for
           a list of supported targets.

           This may also be specified with the build.target config value

           Note that specifying this flag makes Cargo run in a different mode
           where the target artifacts are placed in a separate directory. See
           the build cache
           documentation for more details.

       --target-dir directory
           Directory for all generated artifacts and intermediate files. May
           also be specified with the CARGO_TARGET_DIR environment variable,
           or the build.target-dir config value
           <https://doc.rust-lang.org/cargo/reference/config.html>. Defaults
           to target in the root of the workspace.

   Feature Selection
       The feature flags allow you to control which features are enabled. When
       no feature options are given, the default feature is activated for
       every selected package.

       See the features documentation
       for more details.

       --features features
           Space or comma separated list of features to activate. Features of
           workspace members may be enabled with package-name/feature-name
           syntax. This flag may be specified multiple times, which enables
           all specified features.

           Activate all available features of all selected packages.

           Do not activate the default feature of the selected packages.

   Manifest Options
       --manifest-path path
           Path to the Cargo.toml file. By default, Cargo searches for the
           Cargo.toml file in the current directory or any parent directory.

       --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

           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.

           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

   Miscellaneous Options
       -j N, --jobs N
           Number of parallel jobs to run. May also be specified with the
           build.jobs config value
           <https://doc.rust-lang.org/cargo/reference/config.html>. Defaults
           to the number of CPUs.

   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

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

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

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

           o  always: Always display colors.

           o  never: Never display colors.

           May also be specified with the term.color config value

   Common Options
           If Cargo has been installed with rustup, and the first argument to
           cargo begins with +, it will be interpreted as a rustup toolchain
           name (such as +stable or +nightly). See the rustup documentation
           <https://rust-lang.github.io/rustup/overrides.html> for more
           information about how toolchain overrides work.

       -h, --help
           Prints help information.

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

       See the reference
       for details on environment variables that Cargo reads.

       o  0: Cargo succeeded.

       o  101: Cargo failed to complete.
