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.
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.
-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.
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.
--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.
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-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>.
-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.
-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>.
+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 or PATH
Overrides a Cargo configuration value. The argument
should be in TOML syntax of KEY=VALUE, or provided as a path to an
extra configuration file. This flag may be specified multiple times. See the
command-line overrides section
<https://doc.rust-lang.org/cargo/reference/config.html#command-line-overrides>
for more information.
-h, --help
Prints help information.
-Z flag
Unstable (nightly-only) flags to Cargo. Run cargo -Z
help for details.
