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

       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.

       See thereference <https://doc.rust-lang.org/cargo/reference/environment-variables.html> for details on
       environment variables that Cargo reads.

        1. Update all dependencies in the lockfile:

               cargo update

        2. Update only specific dependencies:

               cargo update foo bar

        3. Set a specific dependency to a specific version:

               cargo update foo --precise 1.2.3

       •  0: Cargo succeeded.

       •  101: Cargo failed to complete.

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

UpdateOptionsspec…
           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 spec, 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 spec is not specified, all dependencies are updated.

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

       --preciseprecise
           When used with spec, 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).

           While not recommended, you can specify a yanked version of a package. When possible, try other
           non-yanked SemVer-compatible versions or seek help from the maintainers of the package.

           A compatible pre-release version can also be specified even when the version requirement in
           Cargo.toml doesn’t contain any pre-release identifier (nightly only).

       -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.

       --dry-run
           Displays what would be updated, but doesn’t actually write the lockfile.

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

       -q, --quiet
           Do not print cargo log messages. May also be specified with the term.quietconfigvalue
           <https://doc.rust-lang.org/cargo/reference/config.html>.

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

   ManifestOptions--manifest-pathpath
           Path to the Cargo.toml file. By default, Cargo searches for the Cargo.toml file in the current
           directory or any parent directory.

       --ignore-rust-version
           Ignore rust-version specification in packages.

       --locked
           Asserts that the exact same dependencies and versions are used as when the existing Cargo.lock file
           was originally generated. Cargo will exit with an error when either of the following scenarios
           arises:

           •  The lock file is missing.

           •  Cargo attempted to change the lock file due to a different dependency resolution.

           It may be used in environments where deterministic builds are desired, such as in CI pipelines.

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

       --frozen
           Equivalent to specifying both --locked and --offline.

   CommonOptions+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 rustupdocumentation
           <https://rust-lang.github.io/rustup/overrides.html> for more information about how toolchain
           overrides work.

       --configKEY=VALUE or PATH
           Overrides a Cargo configuration value. The argument should be in TOML syntax of KEY=VALUE, or
           provided as a path to an extra configuration file. This flag may be specified multiple times. See the
           command-lineoverridessection
           <https://doc.rust-lang.org/cargo/reference/config.html#command-line-overrides> for more information.

       -CPATH
           Changes the current working directory before executing any specified operations. This affects things
           like where cargo looks by default for the project manifest (Cargo.toml), as well as the directories
           searched for discovering .cargo/config.toml, for example. This option must appear before the command
           name, for example cargo-Cpath/to/my-projectbuild.

           This option is only available on the nightlychannel
           <https://doc.rust-lang.org/book/appendix-07-nightly-rust.html> and requires the -Zunstable-options
           flag to enable (see #10098 <https://github.com/rust-lang/cargo/issues/10098>).

       -h, --help
           Prints help information.

       -Zflag
           Unstable (nightly-only) flags to Cargo. Run cargo-Zhelp for details.
