| cargo\-generate\-lockfile \- Generate the lockfile for a package |
| .SH "SYNOPSIS" |
| \fBcargo generate\-lockfile\fR [\fIoptions\fR] |
| .SH "DESCRIPTION" |
| This command will create the \fBCargo.lock\fR lockfile for the current package or |
| workspace. If the lockfile already exists, it will be rebuilt with the latest |
| available version of every package. |
| .sp |
| See also \fBcargo\-update\fR(1) which is also capable of creating a \fBCargo.lock\fR |
| lockfile and has more options for controlling update behavior. |
| .SH "OPTIONS" |
| .SS "Display Options" |
| .sp |
| \fB\-v\fR, |
| \fB\-\-verbose\fR |
| .RS 4 |
| 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 \fBterm.verbose\fR |
| \fIconfig value\fR <https://doc.rust\-lang.org/cargo/reference/config.html>\&. |
| .RE |
| .sp |
| \fB\-q\fR, |
| \fB\-\-quiet\fR |
| .RS 4 |
| Do not print cargo log messages. |
| May also be specified with the \fBterm.quiet\fR |
| \fIconfig value\fR <https://doc.rust\-lang.org/cargo/reference/config.html>\&. |
| .RE |
| .sp |
| \fB\-\-color\fR \fIwhen\fR |
| .RS 4 |
| Control when colored output is used. Valid values: |
| .sp |
| .RS 4 |
| \h'-04'\(bu\h'+02'\fBauto\fR (default): Automatically detect if color support is available on the |
| terminal. |
| .RE |
| .sp |
| .RS 4 |
| \h'-04'\(bu\h'+02'\fBalways\fR: Always display colors. |
| .RE |
| .sp |
| .RS 4 |
| \h'-04'\(bu\h'+02'\fBnever\fR: Never display colors. |
| .RE |

| .RE |
| .SS "Manifest Options" |
| .sp |
| \fB\-\-manifest\-path\fR \fIpath\fR |
| .RS 4 |
| Path to the \fBCargo.toml\fR file. By default, Cargo searches for the |
| \fBCargo.toml\fR file in the current directory or any parent directory. |
| .RE |
| .sp |
| \fB\-\-frozen\fR, |
| \fB\-\-locked\fR |
| .RS 4 |
| Either of these flags requires that the \fBCargo.lock\fR file is |
| up\-to\-date. If the lock file is missing, or it needs to be updated, Cargo will |
| exit with an error. The \fB\-\-frozen\fR flag also prevents Cargo from |
| attempting to access the network to determine if it is out\-of\-date. |
| .sp |
| These may be used in environments where you want to assert that the |
| \fBCargo.lock\fR file is up\-to\-date (such as a CI build) or want to avoid network |
| access. |
| .RE |
| .sp |
| \fB\-\-offline\fR |
| .RS 4 |
| 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. |
| .sp |
| 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 \fBcargo\-fetch\fR(1) command to download dependencies before going |
| offline. |
| .sp |
| May also be specified with the \fBnet.offline\fR \fIconfig value\fR <https://doc.rust\-lang.org/cargo/reference/config.html>\&. |

| \fB+\fR\fItoolchain\fR |
| .RS 4 |
| If Cargo has been installed with rustup, and the first argument to \fBcargo\fR |
| begins with \fB+\fR, it will be interpreted as a rustup toolchain name (such |
| as \fB+stable\fR or \fB+nightly\fR). |
| See the \fIrustup documentation\fR <https://rust\-lang.github.io/rustup/overrides.html> |
| for more information about how toolchain overrides work. |
| .RE |

| \fB\-\-config\fR KEY=VALUE |
| .RS 4 |
| Overrides a Cargo configuration value. |
| .RE |

| \fB\-h\fR, |

| .RS 4 |
| Prints help information. |
| .RE |
| .sp |
| \fB\-Z\fR \fIflag\fR |
| .RS 4 |
| Unstable (nightly\-only) flags to Cargo. Run \fBcargo \-Z help\fR for details. |
