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. The server will
perform additional checks on the crate.
4.The client will poll waiting for the package to appear
in the index, and may timeout. In that case, you will need to check for
completion manually. This timeout does not affect the upload.
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 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.
--locked
Asserts that the exact same dependencies and versions are
used as when the existing
Cargo.lock file was originally generated.
Cargo will exit with an error when either of the following scenarios arises:
•The lock file is missing.
•Cargo attempted to change the lock file due to a
different dependency resolution.
It may be used in environments where deterministic builds are
desired, such as in CI pipelines.
--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>.
--frozen
Equivalent to specifying both --locked and
--offline.
-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. If a string
default is provided, it sets the value back to defaults. 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.
For example if the current package depends on dependencies
fails and works, one of which fails to build, cargo publish
-j1 may or may not build the one that succeeds (depending on which one
of the two builds Cargo picked to run first), whereas cargo publish -j1
--keep-going would definitely run both builds, even if the one run first
fails.
-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.
-C PATH
Changes the current working directory before executing
any specified operations. This affects things like where cargo looks by
default for the project manifest (
Cargo.toml), as well as the
directories searched for discovering
.cargo/config.toml, for example.
This option must appear before the command name, for example
cargo -C
path/to/my-project build.
This option is only available on the nightly channel
<https://doc.rust-lang.org/book/appendix-07-nightly-rust.html> and
requires the -Z unstable-options flag to enable (see #10098
<https://github.com/rust-lang/cargo/issues/10098>).
-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.
