CARGO-PACKAGE(1)

NAME
       cargo-package — Assemble the local package into a distributable
       tarball

SYNOPSIS
       cargo package [options]

DESCRIPTION
       This command will create a distributable, compressed .crate file with
       the source code of the package in the current directory. The resulting
       file will be stored in the target/package directory. This performs the
       following steps:

       1. Load and check the current workspace, performing some basic checks.
          o  Path dependencies are not allowed unless they have a version key.
             Cargo will ignore the path key for dependencies in published
             packages. dev-dependencies do not have this restriction.

       2. Create the compressed .crate file.
          o  The original Cargo.toml file is rewritten and normalized.

          o  [patch], [replace], and [workspace] sections are removed from the
             manifest.

          o  Cargo.lock is automatically included if the package contains an
             executable binary or example target. cargo-install(1) will use the
             packaged lock file if the --locked flag is used.

          o  A .cargo_vcs_info.json file is included that contains information
             about the current VCS checkout hash if available (not included
             with --allow-dirty).

       3. Extract the .crate file and build it to verify it can build.
          o  This will rebuild your package from scratch to ensure that it can
             be built from a pristine state. The --no-verify flag can be used
             to skip this step.

       4. Check that build scripts did not modify any source files.

       The list of files included can be controlled with the include and
       exclude fields in the manifest.

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

   .cargo_vcs_info.json format
       Will generate a .cargo_vcs_info.json in the following format

           {
            "git": {
              "sha1": "aac20b6e7e543e6dd4118b246c77225e3a3a1302"
            },
            "path_in_vcs": ""
           }

       path_in_vcs will be set to a repo-relative path for packages in
       subdirectories of the version control repository.

OPTIONS
   Package Options
       -l, --list
           Print files included in a package without making one.

       --no-verify
           Don’t verify the contents by building them.

       --no-metadata
           Ignore warnings about a lack of human-usable metadata (such as the
           description or the license).

       --allow-dirty
           Allow working directories with uncommitted VCS changes to be
           packaged.

   Package Selection
       By default, when no package selection options are given, the packages
       selected depend on the selected manifest file (based on the current
       working directory if --manifest-path is not given). If the manifest is
       the root of a workspace then the workspaces default members are
       selected, otherwise only the package defined by the manifest will be
       selected.

       The default members of a workspace can be set explicitly with the
       workspace.default-members key in the root manifest. If this is not set,
       a virtual workspace will include all workspace members (equivalent to
       passing --workspace), and a non-virtual workspace will include only the
       root crate itself.

       -p spec…, --package spec…
           Package only the specified packages. See cargo-pkgid(1) for the SPEC
           format. This flag may be specified multiple times and supports
           common Unix glob patterns like *, ? and []. However, to avoid your
           shell accidentally expanding glob patterns before Cargo handles
           them, you must use single quotes or double quotes around each
           pattern.

       --workspace
           Package all members in the workspace.

       --exclude SPEC…
           Exclude the specified packages. Must be used in conjunction with the
           --workspace flag. This flag may be specified multiple times and
           supports common Unix glob patterns like *, ? and []. However, to
           avoid your shell accidentally expanding glob patterns before Cargo
           handles them, you must use single quotes or double quotes around
           each pattern.

   Compilation Options
       --target triple
           Package 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 flag may be specified multiple
           times.

           This may also be specified with the build.target config value
           <https://doc.rust-lang.org/cargo/reference/config.html>.

           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
           <https://doc.rust-lang.org/cargo/guide/build-cache.html>
           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
       <https://doc.rust-lang.org/cargo/reference/features.html#command-line-feature-options>
       for more details.

       -F features, --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.

       --all-features
           Activate all available features of all selected packages.

       --no-default-features
           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
           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>.

   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 logical CPUs. If negative, it sets the maximum number
           of parallel jobs to the number of logical CPUs plus provided value.
           Should not be 0.

       --keep-going
           Build as many crates in the dependency graph as possible, rather
           than aborting the build on the first one that fails to build.
           Unstable, requires -Zunstable-options.

   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
           Do not print cargo log messages. May also be specified with the
           term.quiet config value
           <https://doc.rust-lang.org/cargo/reference/config.html>.

       --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
           <https://doc.rust-lang.org/cargo/reference/config.html>.

   Common Options
       +toolchain
           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.

       --config KEY=VALUE or PATH
           Overrides a Cargo configuration value. The argument should be in
           TOML syntax of KEY=VALUE, or provided as a path to an extra
           configuration file. This flag may be specified multiple times. See
           the command-line overrides section
           <https://doc.rust-lang.org/cargo/reference/config.html#command-line-overrides>
           for more information.

       -C PATH
           Changes the current working directory before executing any specified
           operations. This affects things like where cargo looks by default
           for the project manifest (Cargo.toml), as well as the directories
           searched for discovering .cargo/config.toml, for example. This
           option must appear before the command name, for example cargo -C
           path/to/my-project build.

       -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
       o  0: Cargo succeeded.

       o  101: Cargo failed to complete.

EXAMPLES
       1. Create a compressed .crate file of the current package:

              cargo package
