'\" t .TH "CARGO\-PACKAGE" "1" .nh .ad l .ss \n[.ss] 0 .SH "NAME" cargo\-package \[em] Assemble the local package into a distributable tarball .SH "SYNOPSIS" \fBcargo package\fR [\fIoptions\fR] .SH "DESCRIPTION" This command will create a distributable, compressed \fB\&.crate\fR file with the source code of the package in the current directory. The resulting file will be stored in the \fBtarget/package\fR directory. This performs the following steps: .sp .RS 4 \h'-04' 1.\h'+01'Load and check the current workspace, performing some basic checks. .sp .RS 4 \h'-04'\(bu\h'+02'Path dependencies are not allowed unless they have a version key. Cargo will ignore the path key for dependencies in published packages. \fBdev\-dependencies\fR do not have this restriction. .RE .RE .sp .RS 4 \h'-04' 2.\h'+01'Create the compressed \fB\&.crate\fR file. .sp .RS 4 \h'-04'\(bu\h'+02'The original \fBCargo.toml\fR file is rewritten and normalized. .RE .sp .RS 4 \h'-04'\(bu\h'+02'\fB[patch]\fR, \fB[replace]\fR, and \fB[workspace]\fR sections are removed from the manifest. .RE .sp .RS 4 \h'-04'\(bu\h'+02'\fBCargo.lock\fR is automatically included if the package contains an executable binary or example target. \fBcargo\-install\fR(1) will use the packaged lock file if the \fB\-\-locked\fR flag is used. .RE .sp .RS 4 \h'-04'\(bu\h'+02'A \fB\&.cargo_vcs_info.json\fR file is included that contains information about the current VCS checkout hash if available, as well as a flag if the worktree is dirty. .RE .RE .sp .RS 4 \h'-04' 3.\h'+01'Extract the \fB\&.crate\fR file and build it to verify it can build. .sp .RS 4 \h'-04'\(bu\h'+02'This will rebuild your package from scratch to ensure that it can be built from a pristine state. The \fB\-\-no\-verify\fR flag can be used to skip this step. .RE .RE .sp .RS 4 \h'-04' 4.\h'+01'Check that build scripts did not modify any source files. .RE .sp The list of files included can be controlled with the \fBinclude\fR and \fBexclude\fR fields in the manifest. .sp See \fIthe reference\fR for more details about packaging and publishing. .SS ".cargo_vcs_info.json format" Will generate a \fB\&.cargo_vcs_info.json\fR in the following format .sp .RS 4 .nf { "git": { "sha1": "aac20b6e7e543e6dd4118b246c77225e3a3a1302", "dirty": true }, "path_in_vcs": "" } .fi .RE .sp \fBdirty\fR indicates that the Git worktree was dirty when the package was built. .sp \fBpath_in_vcs\fR will be set to a repo\-relative path for packages in subdirectories of the version control repository. .sp The compatibility of this file is maintained under the same policy as the JSON output of \fBcargo\-metadata\fR(1). .sp 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. .SH "OPTIONS" .SS "Package Options" .sp \fB\-l\fR, \fB\-\-list\fR .RS 4 Print files included in a package without making one. .RE .sp \fB\-\-no\-verify\fR .RS 4 Don\[cq]t verify the contents by building them. .RE .sp \fB\-\-no\-metadata\fR .RS 4 Ignore warnings about a lack of human\-usable metadata (such as the description or the license). .RE .sp \fB\-\-allow\-dirty\fR .RS 4 Allow working directories with uncommitted VCS changes to be packaged. .RE .sp \fB\-\-index\fR \fIindex\fR .RS 4 The URL of the registry index to use. .RE .sp \fB\-\-registry\fR \fIregistry\fR .RS 4 Name of the registry to package for; see \fBcargo publish \-\-help\fR for more details about configuration of registry names. The packages will not be published to this registry, but if we are packaging multiple inter\-dependent crates, lock\-files will be generated under the assumption that dependencies will be published to this registry. .RE .SS "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 \fB\-\-manifest\-path\fR 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. .sp The default members of a workspace can be set explicitly with the \fBworkspace.default\-members\fR key in the root manifest. If this is not set, a virtual workspace will include all workspace members (equivalent to passing \fB\-\-workspace\fR), and a non\-virtual workspace will include only the root crate itself. .sp \fB\-p\fR \fIspec\fR\[u2026], \fB\-\-package\fR \fIspec\fR\[u2026] .RS 4 Package only the specified packages. See \fBcargo\-pkgid\fR(1) for the SPEC format. This flag may be specified multiple times and supports common Unix glob patterns like \fB*\fR, \fB?\fR and \fB[]\fR\&. However, to avoid your shell accidentally expanding glob patterns before Cargo handles them, you must use single quotes or double quotes around each pattern. .RE .sp \fB\-\-workspace\fR .RS 4 Package all members in the workspace. .RE .sp \fB\-\-exclude\fR \fISPEC\fR\[u2026] .RS 4 Exclude the specified packages. Must be used in conjunction with the \fB\-\-workspace\fR flag. This flag may be specified multiple times and supports common Unix glob patterns like \fB*\fR, \fB?\fR and \fB[]\fR\&. However, to avoid your shell accidentally expanding glob patterns before Cargo handles them, you must use single quotes or double quotes around each pattern. .RE .SS "Compilation Options" .sp \fB\-\-target\fR \fItriple\fR .RS 4 Package for the given architecture. The default is the host architecture. The general format of the triple is \fB\-\-\-\fR\&. Run \fBrustc \-\-print target\-list\fR for a list of supported targets. This flag may be specified multiple times. .sp This may also be specified with the \fBbuild.target\fR \fIconfig value\fR \&. .sp Note that specifying this flag makes Cargo run in a different mode where the target artifacts are placed in a separate directory. See the \fIbuild cache\fR documentation for more details. .RE .sp \fB\-\-target\-dir\fR \fIdirectory\fR .RS 4 Directory for all generated artifacts and intermediate files. May also be specified with the \fBCARGO_TARGET_DIR\fR environment variable, or the \fBbuild.target\-dir\fR \fIconfig value\fR \&. Defaults to \fBtarget\fR in the root of the workspace. .RE .SS "Feature Selection" The feature flags allow you to control which features are enabled. When no feature options are given, the \fBdefault\fR feature is activated for every selected package. .sp See \fIthe features documentation\fR for more details. .sp \fB\-F\fR \fIfeatures\fR, \fB\-\-features\fR \fIfeatures\fR .RS 4 Space or comma separated list of features to activate. Features of workspace members may be enabled with \fBpackage\-name/feature\-name\fR syntax. This flag may be specified multiple times, which enables all specified features. .RE .sp \fB\-\-all\-features\fR .RS 4 Activate all available features of all selected packages. .RE .sp \fB\-\-no\-default\-features\fR .RS 4 Do not activate the \fBdefault\fR feature of the selected packages. .RE .SS "Manifest Options" .sp \fB\-\-manifest\-path\fR \fIpath\fR .RS 4 Path to the \fBCargo.toml\fR file. By default, Cargo searches for the \fBCargo.toml\fR file in the current directory or any parent directory. .RE .sp \fB\-\-locked\fR .RS 4 Asserts that the exact same dependencies and versions are used as when the existing \fBCargo.lock\fR file was originally generated. Cargo will exit with an error when either of the following scenarios arises: .sp .RS 4 \h'-04'\(bu\h'+02'The lock file is missing. .RE .sp .RS 4 \h'-04'\(bu\h'+02'Cargo attempted to change the lock file due to a different dependency resolution. .RE .sp It may be used in environments where deterministic builds are desired, such as in CI pipelines. .RE .sp \fB\-\-offline\fR .RS 4 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. .sp 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 \fBcargo\-fetch\fR(1) command to download dependencies before going offline. .sp May also be specified with the \fBnet.offline\fR \fIconfig value\fR \&. .RE .sp \fB\-\-frozen\fR .RS 4 Equivalent to specifying both \fB\-\-locked\fR and \fB\-\-offline\fR\&. .RE .sp \fB\-\-lockfile\-path\fR \fIPATH\fR .RS 4 Changes the path of the lockfile from the default (\fB/Cargo.lock\fR) to \fIPATH\fR\&. \fIPATH\fR must end with \fBCargo.lock\fR (e.g. \fB\-\-lockfile\-path /tmp/temporary\-lockfile/Cargo.lock\fR). Note that providing \fB\-\-lockfile\-path\fR will ignore existing lockfile at the default path, and instead will either use the lockfile from \fIPATH\fR, or write a new lockfile into the provided \fIPATH\fR if it doesn\[cq]t exist. This flag can be used to run most commands in read\-only directories, writing lockfile into the provided \fIPATH\fR\&. .sp This option is only available on the \fInightly channel\fR and requires the \fB\-Z unstable\-options\fR flag to enable (see \fI#14421\fR ). .RE .SS "Miscellaneous Options" .sp \fB\-j\fR \fIN\fR, \fB\-\-jobs\fR \fIN\fR .RS 4 Number of parallel jobs to run. May also be specified with the \fBbuild.jobs\fR \fIconfig value\fR \&. 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. If a string \fBdefault\fR is provided, it sets the value back to defaults. Should not be 0. .RE .sp \fB\-\-keep\-going\fR .RS 4 Build as many crates in the dependency graph as possible, rather than aborting the build on the first one that fails to build. .sp For example if the current package depends on dependencies \fBfails\fR and \fBworks\fR, one of which fails to build, \fBcargo package \-j1\fR may or may not build the one that succeeds (depending on which one of the two builds Cargo picked to run first), whereas \fBcargo package \-j1 \-\-keep\-going\fR would definitely run both builds, even if the one run first fails. .RE .SS "Display Options" .sp \fB\-v\fR, \fB\-\-verbose\fR .RS 4 Use verbose output. May be specified twice for \[lq]very verbose\[rq] output which includes extra output such as dependency warnings and build script output. May also be specified with the \fBterm.verbose\fR \fIconfig value\fR \&. .RE .sp \fB\-q\fR, \fB\-\-quiet\fR .RS 4 Do not print cargo log messages. May also be specified with the \fBterm.quiet\fR \fIconfig value\fR \&. .RE .sp \fB\-\-color\fR \fIwhen\fR .RS 4 Control when colored output is used. Valid values: .sp .RS 4 \h'-04'\(bu\h'+02'\fBauto\fR (default): Automatically detect if color support is available on the terminal. .RE .sp .RS 4 \h'-04'\(bu\h'+02'\fBalways\fR: Always display colors. .RE .sp .RS 4 \h'-04'\(bu\h'+02'\fBnever\fR: Never display colors. .RE .sp May also be specified with the \fBterm.color\fR \fIconfig value\fR \&. .RE .SS "Common Options" .sp \fB+\fR\fItoolchain\fR .RS 4 If Cargo has been installed with rustup, and the first argument to \fBcargo\fR begins with \fB+\fR, it will be interpreted as a rustup toolchain name (such as \fB+stable\fR or \fB+nightly\fR). See the \fIrustup documentation\fR for more information about how toolchain overrides work. .RE .sp \fB\-\-config\fR \fIKEY=VALUE\fR or \fIPATH\fR .RS 4 Overrides a Cargo configuration value. The argument should be in TOML syntax of \fBKEY=VALUE\fR, or provided as a path to an extra configuration file. This flag may be specified multiple times. See the \fIcommand\-line overrides section\fR for more information. .RE .sp \fB\-C\fR \fIPATH\fR .RS 4 Changes the current working directory before executing any specified operations. This affects things like where cargo looks by default for the project manifest (\fBCargo.toml\fR), as well as the directories searched for discovering \fB\&.cargo/config.toml\fR, for example. This option must appear before the command name, for example \fBcargo \-C path/to/my\-project build\fR\&. .sp This option is only available on the \fInightly channel\fR and requires the \fB\-Z unstable\-options\fR flag to enable (see \fI#10098\fR ). .RE .sp \fB\-h\fR, \fB\-\-help\fR .RS 4 Prints help information. .RE .sp \fB\-Z\fR \fIflag\fR .RS 4 Unstable (nightly\-only) flags to Cargo. Run \fBcargo \-Z help\fR for details. .RE .SH "ENVIRONMENT" See \fIthe reference\fR for details on environment variables that Cargo reads. .SH "EXIT STATUS" .sp .RS 4 \h'-04'\(bu\h'+02'\fB0\fR: Cargo succeeded. .RE .sp .RS 4 \h'-04'\(bu\h'+02'\fB101\fR: Cargo failed to complete. .RE .SH "EXAMPLES" .sp .RS 4 \h'-04' 1.\h'+01'Create a compressed \fB\&.crate\fR file of the current package: .sp .RS 4 .nf cargo package .fi .RE .RE .SH "SEE ALSO" \fBcargo\fR(1), \fBcargo\-publish\fR(1)
