| All the arguments following the two dashes (\fB\-\-\fP) are passed to the binary to |
| run. If you\(cqre passing arguments to both Cargo and the binary, the ones after |
| \fB\-\-\fP go to the binary, the ones before go to Cargo. |
| .SH "OPTIONS" |

| package. |
| .RE |
| .SS "Compilation Options" |
| .sp |
| \fB\-\-target\fP \fITRIPLE\fP |
| .RS 4 |
| Run for the given architecture. The default is the host |
| architecture. The general format of the triple is |
| \fB<arch><sub>\-<vendor>\-<sys>\-<abi>\fP. Run \fBrustc \-\-print target\-list\fP for a |

| \fBjson\-render\-diagnostics\fP: Instruct Cargo to not include rustc diagnostics in |

| .SS "Manifest Options" |
| .sp |
| \fB\-\-manifest\-path\fP \fIPATH\fP |
| .RS 4 |
| Path to the \fBCargo.toml\fP file. By default, Cargo searches in the current |
| directory or any parent directory for the \fBCargo.toml\fP file. |
| .RE |
| .sp |
| \fB\-\-frozen\fP, \fB\-\-locked\fP |
| .RS 4 |
| Either of these flags requires that the \fBCargo.lock\fP 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\fP 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\fP file is up\-to\-date (such as a CI build) or want to avoid network |
| access. |
| .RE |
| .sp |
| \fB\-\-offline\fP |
| .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\fP(1) command to download dependencies before going |
| offline. |

| .sp |
| \fB\-j\fP \fIN\fP, \fB\-\-jobs\fP \fIN\fP |

| Number of parallel jobs to run. May also be specified with the |

| for more details. |
| .sp |
| Profile selection depends on the target and crate being built. By default the |
| \fBdev\fP or \fBtest\fP profiles are used. If the \fB\-\-release\fP flag is given, then the |
| \fBrelease\fP or \fBbench\fP profiles are used. |
