cargo-publish - Upload a package to the registry
This command will create a distributable, compressed .crate file with the
source code of the package in the current directory and upload it to a
registry. The default registry is <https://crates.io>. This performs the
following steps:
1.Performs a few checks, including:
•Checks the package.publish key in the
manifest for restrictions on which registries you are allowed to publish
to.
2.Create a .crate file by following the steps in
cargo-package(1).
3.Upload the crate to the registry. Note that the server
will perform additional checks on the crate.
This command requires you to be authenticated with either the
--token option or using cargo-login(1).
See the reference
<https://doc.rust-lang.org/cargo/reference/publishing.html> for more
details about packaging and publishing.
--dry-run
Perform all checks without uploading.
--token token
API token to use when authenticating. This overrides the
token stored in the credentials file (which is created by
cargo-login(1)).
Cargo config
<https://doc.rust-lang.org/cargo/reference/config.html> environment
variables can be used to override the tokens stored in the credentials file.
The token for crates.io may be specified with the
CARGO_REGISTRY_TOKEN environment variable. Tokens for other
registries may be specified with environment variables of the form
CARGO_REGISTRIES_NAME_TOKEN where NAME is the name of the
registry in all capital letters.
--no-verify
Don't verify the contents by building them.
--allow-dirty
Allow working directories with uncommitted VCS changes to
be packaged.
--index index
The URL of the registry index to use.
--registry registry
Name of the registry to publish to. Registry names are
defined in Cargo config files
<https://doc.rust-lang.org/cargo/reference/config.html>. If not
specified, and there is a package.publish
<https://doc.rust-lang.org/cargo/reference/manifest.html#the-publish-field>
field in Cargo.toml with a single registry, then it will publish to
that registry. Otherwise it will use the default registry, which is defined by
the registry.default
<https://doc.rust-lang.org/cargo/reference/config.html#registrydefault>
config key which defaults to crates-io.
By default, the package in the current working directory is selected. The
-p flag can be used to choose a different package in a workspace.
-p spec, --package spec
The package to publish. See cargo-pkgid(1) for the
SPEC format.
--target triple
Publish 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 <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.
--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>.
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 CPUs.
-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>.
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.
-h, --help
Prints help information.
-Z flag
Unstable (nightly-only) flags to Cargo. Run cargo -Z
help for details.
See the reference
<https://doc.rust-lang.org/cargo/reference/environment-variables.html>
for details on environment variables that Cargo reads.
•0: Cargo succeeded.
•101: Cargo failed to complete.
