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:
    • 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 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 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. If not specified, and there is a package.publish 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 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
为指定架构执行 Publish 。默认情况下为本机的架构。三元组的格式为 <arch><sub>-<vendor>-<sys>-<abi>。执行 rustc --print target-list 可得到支持的构建目标列表。

也可通过build.target指定(config value)。

注意，指定该标志参数会使Cargo产生的构建工件放在与平常不同的目录下。 详情参见build cache

--target-dir directory
用于存放生成的工件以及中间文件的目录。也可通过环境变量CARGO_TARGET_DIR 或 build.target-dir config value指定。

默认情况下为根工作区中的target目录。

特性选择

可通过传递特性参数来控制启用哪些特性。如果没有给定要使用的特性， 则每个已选择的包都会自动使用default特性。

详见the features documentation。

--features features
传递以空格或者逗号分隔的列表，其中给出要启用的特性。工作区成员的特性可通过包名/特性名的语法启用。 此参数可多次给定，以分别启用给定的特性。
--all-features
为给定的包启用全部可用特性
--no-default-features
不启用给定包的default特性

Manifest Options

--manifest-path path
用于指定Cargo.toml文件的路径。默认情况下，Cargo会在当前目录或上级目录中寻找Cargo.toml文件。
--frozen
--locked
这两个选项用于保证Cargo.lock文件是最新的。如果该锁文件不存在，或者不是最新的，Cargo 会报错退出。其中--frozen选项会阻止Cargo访问网络以检查锁文件是否是最新的。

这些选项，可用于保证Cargo.lock文件是最新的(比如持续集成的构建过程)， 或用于避免联网。

--offline
禁止Cargo访问网络。如果不添加此选项，Cargo在需要访问网络但网络不可用的情况下，会报错 并停止工作。添加此选项后，Cargo会尽可能尝试不使用网络来工作。

注意，在此情况下可能会产生与联网状态下不同的依赖解析(Dependency Resolution)结果。 Cargo只会使用本地已下载的crate，即便本地的索引副本中表明可能有新版本crate。在离线前下载 所需依赖的方法，参见 cargo-fetch(1) 。

也可以通过 net.offline config value指定。

Miscellaneous Options

-j N
--jobs N
要并行运行的作业数量。也可通过build.jobs config value指定。 默认为CPU数量。

Display Options

-v
--verbose
启用更加详细的输出。可两次使用来显示"非常详细"的输出，其中包含了诸如 依赖警告 以及 构建脚本输出 等额外的输出内容。 也可通过term.verbose指定。 config value.
-q
--quiet
不输出Cargo的日志信息。也可通过term.quiet指定。 config value.
--color when
控制输出内容的颜色。有效取值如下：

  • auto (默认)：自动检测终端是否支持带颜色的输出。
  • always：总显示带颜色的输出。
  • never：从不显示带颜色的输出。

也可通过term.color指定。 config value.

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 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.

环境

关于Cargo所读取的环境变量，可参见the reference

退出状态

  • 0: Cargo命令执行成功
  • 101: Cargo命令未能完成.

EXAMPLES

  1. Publish the current package:

    cargo publish
