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:

           •  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.

       --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.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

       •  0: Cargo succeeded.

       •  101: Cargo failed to complete.

EXAMPLES

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