cargo publish
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:
-
Performs a few checks, including:
-
Checks the
package.publish
key in the manifest for restrictions on which registries you are allowed to publish to.
-
-
Create a
.crate
file by following the steps in cargo-package(1). -
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 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 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 formCARGO_REGISTRIES_NAME_TOKEN
whereNAME
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 use. Registry names are defined in Cargo config files. If not specified, the default registry is used, which is defined by the
registry.default
config key which defaults tocrates-io
.
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>
. Runrustc --print target-list
for a list of supported targets.This may also be specified with the
build.target
config value. - --target-dir DIRECTORY
-
Directory for all generated artifacts and intermediate files. May also be specified with the
CARGO_TARGET_DIR
environment variable, or thebuild.target-dir
config value. Defaults totarget
in the root of the workspace.
Feature Selection
When no feature options are given, the default
feature is activated for
every selected package.
- --features FEATURES
-
Space or comma separated list of features to activate. These features only apply to the current directory’s package. Features of direct dependencies may be enabled with
<dep-name>/<feature-name>
syntax. - --all-features
-
Activate all available features of all selected packages.
- --no-default-features
-
Do not activate the
default
feature of the current directory’s package.
Manifest Options
- --manifest-path PATH
-
Path to the
Cargo.toml
file. By default, Cargo searches in the current directory or any parent directory for theCargo.toml
file. - --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.
Miscellaneous Options
- -j N
- --jobs N
-
Number of parallel jobs to run. May also be specified with the
build.jobs
config value. Defaults to the number of CPUs.
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. - -q
- --quiet
-
No output printed to stdout.
- --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. -
