.SH "NAME"
cargo\-fetch \- Fetch dependencies of a package from the network
.SH "SYNOPSIS"
.sp
\fBcargo fetch [\fIOPTIONS\fP]\fP
.SH "DESCRIPTION"
.sp
If a \fBCargo.lock\fP file is available, this command will ensure that all of the
git dependencies and/or registry dependencies are downloaded and locally
available. Subsequent Cargo commands never touch the network after a \fBcargo
fetch\fP unless the lock file changes.
.sp
If the lock file is not available, then this command will generate the lock
file before fetching the dependencies.
.sp
If \fB\-\-target\fP is not specified, then all target dependencies are fetched.
.SH "OPTIONS"
.SS "Fetch options"
.sp
\fB\-\-target\fP \fITRIPLE\fP
.RS 4
Fetch 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
list of supported targets.
.sp
This may also be specified with the \fBbuild.target\fP
.URL "https://doc.rust\-lang.org/cargo/reference/config.html" "config value" "."
.RE
.SS "Display Options"
.sp
\fB\-v\fP, \fB\-\-verbose\fP
.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\fP
.URL "https://doc.rust\-lang.org/cargo/reference/config.html" "config value" "."
.RE
.sp
\fB\-q\fP, \fB\-\-quiet\fP
.RS 4
No output printed to stdout.
.RE
.sp
\fB\-\-color\fP \fIWHEN\fP
.RS 4
Control when colored output is used. Valid values:
.sp
.RS 4
.ie n \{\
\h'-04'\(bu\h'+03'\c
.\}
.el \{\
.  sp -1
.  IP \(bu 2.3
.\}
\fBauto\fP (default): Automatically detect if color support is available on the
terminal.
.RE
.sp
.RS 4
.ie n \{\
\h'-04'\(bu\h'+03'\c
.\}
.el \{\
.  sp -1
.  IP \(bu 2.3
.\}
\fBalways\fP: Always display colors.
.RE
.sp
.RS 4
.ie n \{\
\h'-04'\(bu\h'+03'\c
.\}
.el \{\
.  sp -1
.  IP \(bu 2.3
.\}
\fBnever\fP: Never display colors.
.RE
.sp
May also be specified with the \fBterm.color\fP
.URL "https://doc.rust\-lang.org/cargo/reference/config.html" "config value" "."
.RE
.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
.SS "Common Options"
.sp
\fB\-h\fP, \fB\-\-help\fP
.RS 4
Prints help information.
.RE
.sp
\fB\-Z\fP \fIFLAG\fP...
.RS 4
Unstable (nightly\-only) flags to Cargo. Run \fBcargo \-Z help\fP for
details.
.RE
.SH "ENVIRONMENT"
.sp
See \c
.URL "https://doc.rust\-lang.org/cargo/reference/environment\-variables.html" "the reference" " "
for
details on environment variables that Cargo reads.
.SH "EXIT STATUS"
.sp

.RS 4
