cargo-pkgid - Print a fully qualified package specification
cargo pkgid [options] [spec]
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:
-p spec, --package spec
Get the package ID for the given package instead of the
No output printed to stdout.
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
Path to the Cargo.toml file. By default, Cargo
searches for the Cargo.toml file in the current directory or any parent
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from attempting to access the network to determine if it is out-of-date.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.
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
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
). See the
for more information
about how toolchain overrides work.
Prints help information.
