CARGO-GENERATE-LOCKFILE(1)

NAME
       cargo-generate-lockfile — Generate the lockfile for a package

SYNOPSIS
       cargo generate-lockfile [options]

DESCRIPTION
       This command will create the Cargo.lock lockfile for the current package
       or workspace. If the lockfile already exists, it will be rebuilt with
       the latest available version of every package.

       See also cargo-update(1) which is also capable of creating a Cargo.lock
       lockfile and has more options for controlling update behavior.

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

       --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
           <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.

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

       --publish-time yyyy-mm-ddThh:mm:ssZ
           Latest publish time allowed for registry packages (Unstable)

           This is a best-effort filter on allowed packages, including:

           o  packages from unsupported registries are always accepted

           o  only the current yank state is respected, not the state as of
              --publish-time

           o  precision of the publish time

       --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:

           o  The lock file is missing.

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

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

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

       --config KEY=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-line overrides section
           <https://doc.rust-lang.org/cargo/reference/config.html#command-line-overrides>
           for more information.

       -C PATH
           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 -C
           path/to/my-project build.

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

       -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
       o  0: Cargo succeeded.

       o  101: Cargo failed to complete.

EXAMPLES
       1. Create or update the lockfile for the current package or workspace:

              cargo generate-lockfile
