cargo-generate-lockfile — Generate the lockfile for a
package
cargo generate-lockfile [options]
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.
-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-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.
+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.
See the reference
<https://doc.rust-lang.org/cargo/reference/environment-variables.html>
for details on environment variables that Cargo reads.
•0: Cargo succeeded.
•101: Cargo failed to complete.
