NAME

cargo pkgid-打印完全合格的包装规格

SYNOPSIS

cargo pkgid [options][spec]

DESCRIPTION

给予规格参数，打印出当前工作区中包或依赖项的完全限定包ID说明符。如果规格它在依赖关系图中引用的包不明确。如果没有规格，然后打印本地包的说明符。

此命令要求锁文件可用，并且已获取依赖项。

包说明符由名称、版本和源URL组成。您可以使用部分说明符简洁地匹配特定的包，只要它只匹配一个包。文件的格式规格可以是以下内容之一：

规格结构 示例规范
名称 bitflags
名称:版本 bitflags:1.0.4
网址 https://github.com/rust-lang/cargo
网址#版本 https://github.com/rust-lang/cargo#0.33.0
网址#名称 https://github.com/rust-lang/crates.io-index#bitflags
网址#名称:版本 https://github.com/rust-lang/cargo#crates-io:0.21.0

OPTIONS

Package Selection

-p spec
--package spec
Get the package ID for the given package instead of the current package.

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
Do not print cargo log messages. May also be specified with the term.quiet config value.
--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.

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 The --frozen flag also prevents Cargo from attempting to access the network to determine if it is out-of-date.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.

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.
