       cargo-update - Update dependencies as recorded in the local lock	file

       cargo update [options]

       This command will update	dependencies in	the Cargo.lock file to the
       latest version. If the Cargo.lock file does not exist, it will be
       created with the	latest available versions.

   Update Options
       -p spec..., --package spec...
	   Update only the specified packages. This flag may be	specified
	   multiple times. See cargo-pkgid(1) for the SPEC format.

	   If packages are specified with the -p flag, then a conservative
	   update of the lockfile will be performed. This means	that only the
	   dependency specified	by SPEC	will be	updated. Its transitive
	   dependencies	will be	updated	only if	SPEC cannot be updated without
	   updating dependencies. All other dependencies will remain locked at
	   their currently recorded versions.

	   If -p is not	specified, all dependencies are	updated.

	   When	used with -p, dependencies of spec are forced to update	as
	   well. Cannot	be used	with --precise.

       --precise precise
	   When	used with -p, allows you to specify a specific version number
	   to set the package to. If the package comes from a git repository,
	   this	can be a git revision (such as a SHA hash or tag).

       -w, --workspace
	   Attempt to update only packages defined in the workspace. Other
	   packages are	updated	only if	they don't already exist in the
	   lockfile. This option is useful for updating	Cargo.lock after
	   you've changed version numbers in Cargo.toml.

	   Displays what would be updated, but doesn't actually	write the

   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
	   No output printed to	stdout.

       --color when
	   Control when	colored	output is used.	Valid values:

	   o  auto (default): Automatically detect if color support is
	       available on the	terminal.

	   o  always: Always display colors.

	   o  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

	   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 value

   Common Options
	   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

       See the reference
       for details on environment variables that Cargo reads.

       o  0: Cargo succeeded.

       o  101: Cargo failed to complete.

	1. Update all dependencies in the lockfile:

	       cargo update

	2. Update only specific	dependencies:

	       cargo update -p foo -p bar

	3. Set a specific dependency to	a specific version:

	       cargo update -p foo --precise 1.2.3
