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.
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>.
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>.
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>.
Path to the Cargo.toml file. By default, Cargo searches for the Cargo.toml file in the current directory or any parent directory.
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 out−of−date.
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 <https://doc.rust−lang.org/cargo/reference/config.html>.
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.
Overrides a Cargo configuration value.
Prints help information.
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.
