6 cargo-pkgid - Print a fully qualified package specification
7
9 cargo pkgid [options] [spec]
10
12 Given a spec argument, print out the fully qualified package ID
13 specifier for a package or dependency in the current workspace. This
14 command will generate an error if spec is ambiguous as to which package
15 it refers to in the dependency graph. If no spec is given, then the
16 specifier for the local package is printed.
17 This command requires that a lockfile is available and dependencies
19 have been fetched.
20 A package specifier consists of a name, version, and source URL. You
22 are allowed to use partial specifiers to succinctly match a specific
23 package as long as it matches only one package. The format of a spec
24 can be one of the following:
25 ┌─────────────────┬───────────────────────────────────────────────────────┐

44 Package Selection
45 -p spec, --package spec
46 Get the package ID for the given package instead of the current
47 package.
48 Display Options
50 -v, --verbose
51 Use verbose output. May be specified twice for "very verbose"
52 output which includes extra output such as dependency warnings and
53 build script output. May also be specified with the term.verbose
54 config value
55 <https://doc.rust-lang.org/cargo/reference/config.html>.
56 -q, --quiet
58 No output printed to stdout.
59 --color when
61 Control when colored output is used. Valid values:
62 · auto (default): Automatically detect if color support is
64 available on the terminal.
65 · always: Always display colors.
67 · never: Never display colors.
69 May also be specified with the term.color config value
71 <https://doc.rust-lang.org/cargo/reference/config.html>.
72 Manifest Options
74 --manifest-path path
75 Path to the Cargo.toml file. By default, Cargo searches for the
76 Cargo.toml file in the current directory or any parent directory.
77 --frozen, --locked
79 Either of these flags requires that the Cargo.lock file is
80 up-to-date. If the lock file is missing, or it needs to be updated,
81 Cargo will exit with an error. The --frozen flag also prevents
82 Cargo from attempting to access the network to determine if it is
83 out-of-date.
84 These may be used in environments where you want to assert that the
86 Cargo.lock file is up-to-date (such as a CI build) or want to avoid
87 network access.
88 --offline
90 Prevents Cargo from accessing the network for any reason. Without
91 this flag, Cargo will stop with an error if it needs to access the
92 network and the network is not available. With this flag, Cargo
93 will attempt to proceed without the network if possible.
94 Beware that this may result in different dependency resolution than
96 online mode. Cargo will restrict itself to crates that are
97 downloaded locally, even if there might be a newer version as
98 indicated in the local copy of the index. See the cargo-fetch(1)
99 command to download dependencies before going offline.
100 May also be specified with the net.offline config value
102 <https://doc.rust-lang.org/cargo/reference/config.html>.
103 Common Options
105 +toolchain
106 If Cargo has been installed with rustup, and the first argument to
107 cargo begins with +, it will be interpreted as a rustup toolchain
108 name (such as +stable or +nightly). See the rustup documentation
109 <https://rust-lang.github.io/rustup/overrides.html> for more
110 information about how toolchain overrides work.
111 -h, --help
113 Prints help information.
114 -Z flag
116 Unstable (nightly-only) flags to Cargo. Run cargo -Z help for
117 details.
118
120 See the reference
121 <https://doc.rust-lang.org/cargo/reference/environment-variables.html>
122 for details on environment variables that Cargo reads.
