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 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

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.

Compilation Options

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 for more details.
