cargo-publish(1) General Commands Manual cargo-publish(1)
NAME
cargo-publish -- Upload a package to the registry
SYNOPSIS
cargo publish [options]
DESCRIPTION
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:
o 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.
OPTIONS
Publish Options
--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.
Package Selection
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.
Compilation Options
--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.
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
<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 Options
--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>.
Miscellaneous Options
-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.
Display 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:
o auto (default): Automatically detect if color support is
available on the terminal.
o always: Always display colors.
o never: Never display colors.
May also be specified with the term.color config value
<https://doc.rust-lang.org/cargo/reference/config.html>.
Common Options
+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.
ENVIRONMENT
See the reference
<https://doc.rust-lang.org/cargo/reference/environment-variables.html>
for details on environment variables that Cargo reads.
EXIT STATUS
o 0: Cargo succeeded.
o 101: Cargo failed to complete.
