cargo package

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.

  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 for more details about packaging and publishing.

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.

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

--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. Defaults to target in the root of the workspace.

Feature Selection

When no feature options are given, the default feature is activated for every selected package.

--features FEATURES

Space or comma separated list of features to activate. These features only apply to the current directory’s package. Features of direct dependencies may be enabled with <dep-name>/<feature-name> syntax.

--all-features

Activate all available features of all selected packages.

--no-default-features

Do not activate the default feature of the current directory’s package.

Manifest Options

--manifest-path PATH

Path to the Cargo.toml file. By default, Cargo searches in the current directory or any parent directory for the Cargo.toml file.

--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.

Miscellaneous Options

-j N
--jobs N

Number of parallel jobs to run. May also be specified with the build.jobs config value. 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:

  • 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.

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 for details on environment variables that Cargo reads.

Exit Status

0

Cargo succeeded.

101

Cargo failed to complete.
