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.

        • 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.

        • The original Cargo.toml file is rewritten and normalized.

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

        • 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.

        • 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.

        • 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:

        • 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>.

  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
    Overrides a Cargo configuration value.

-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.

EXAMPLES

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