# 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 always included. When missing, a new lock file will be
      generated unless the `--exclude-lockfile` flag is used. [cargo-install(1)](cargo-install.html)
      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, as well as a flag if the
      worktree is dirty.
    - Symlinks are flattened to their target files.
    - Files and directories are included or excluded based on rules mentioned in
      [the `[include]` and `[exclude]` fields](../reference/manifest.html#the-exclude-and-include-fields).

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](../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

```javascript
{
 "git": {
   "sha1": "aac20b6e7e543e6dd4118b246c77225e3a3a1302",
   "dirty": true
 },
 "path_in_vcs": ""
}
```

`dirty` indicates that the Git worktree was dirty when the package
was built.

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

The compatibility of this file is maintained under the same policy
as the JSON output of [cargo-metadata(1)](cargo-metadata.html).

Note that this file provides a best-effort snapshot of the VCS information.
However, the provenance of the package is not verified.
There is no guarantee that the source code in the tarball matches the VCS information.

### 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.

SPEC format. This flag may be specified multiple times and supports common Unix
glob patterns like <code>*</code>, <code>?</code> and <code>[]</code>. However, to avoid your shell accidentally
expanding glob patterns before Cargo handles them, you must use single quotes or
double quotes around each pattern.</p>
</dd>


<dt class="option-term" id="option-cargo-package---workspace"><a class="option-anchor" href="#option-cargo-package---workspace"><code>--workspace</code></a></dt>

### Compilation Options

<dl>

<dd class="option-desc"><p>Package for the specified target architecture. Flag may be specified multiple times. The default is the host architecture. The general format of the triple is
<code>&lt;arch&gt;&lt;sub&gt;-&lt;vendor&gt;-&lt;sys&gt;-&lt;abi&gt;</code>.</p>
<p>Possible values:</p>
<ul>
<li>Any supported target in <code>rustc --print target-list</code>.</li>
<li><code>"host-tuple"</code>, which will internally be substituted by the host’s target. This can be particularly useful if you’re cross-compiling some crates, and don’t want to specify your host’s machine as a target (for instance, an <code>xtask</code> in a shared project that may be worked on by many hosts).</li>
<li>A path to a custom target specification. See <a href="../../rustc/targets/custom.html#custom-target-lookup-path">Custom Target Lookup Path</a> for more information.</li>
</ul>
<p>This may also be specified with the <code>build.target</code> <a href="../reference/config.html">config value</a>.</p>
<p>Note that specifying this flag makes Cargo run in a different mode where the
target artifacts are placed in a separate directory. See the
<a href="../reference/build-cache.html">build cache</a> documentation for more details.</p>
</dd>


<dt class="option-term" id="option-cargo-package---target-dir"><a class="option-anchor" href="#option-cargo-package---target-dir"><code>--target-dir</code> <em>directory</em></a></dt>

### 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.

<dd class="option-desc"><p>Space or comma separated list of features to activate. Features of workspace
members may be enabled with <code>package-name/feature-name</code> syntax. This flag may

<dd class="option-desc"><p>Asserts that the exact same dependencies and versions are used as when the
existing <code>Cargo.lock</code> file was originally generated. Cargo will exit with an
error when either of the following scenarios arises:</p>
<ul>
<li>The lock file is missing.</li>
<li>Cargo attempted to change the lock file due to a different dependency resolution.</li>
</ul>
<p>It may be used in environments where deterministic builds are desired,
such as in CI pipelines.</p>

<dd class="option-desc"><p>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.</p>
<p>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 <a href="cargo-fetch.html">cargo-fetch(1)</a> command to download dependencies before going
offline.</p>
<p>May also be specified with the <code>net.offline</code> <a href="../reference/config.html">config value</a>.</p>
