NAME

       cargo-pkgid - Print a fully qualified package specification

SYNOPSIS

       cargo pkgid [OPTIONS] [SPEC]

DESCRIPTION

       Given a SPEC argument, print out the fully qualified package ID specifier for a package or
       dependency in the current workspace. This command will generate an error if SPEC is
       ambiguous as to which package it refers to in the dependency graph. If no SPEC is given,
       then the specifier for the local package is printed.

       This command requires that a lockfile is available and dependencies have been fetched.

       A package specifier consists of a name, version, and source URL. You are allowed to use
       partial specifiers to succinctly match a specific package as long as it matches only one
       package. The format of a SPEC can be one of the following:

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
           <https://doc.rust-lang.org/cargo/reference/config.html>.

       -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
           <https://doc.rust-lang.org/cargo/reference/config.html>.

   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           if it is out-of-date.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>.

   Common Options
       -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

       0
           Cargo succeeded.

       101
           Cargo failed to complete.

EXAMPLES

        1. Retrieve package specification for foo package:

               cargo pkgid foo

        2. Retrieve package specification for version 1.0.0 of foo:

               cargo pkgid foo:1.0.0

        3. Retrieve package specification for foo from crates.io:
