.SH "NAME"
cargo\-rustdoc \- Build a package\(aqs documentation, using specified custom flags
.SH "SYNOPSIS"
.sp
\fBcargo rustdoc [\fIOPTIONS\fP] [\-\- \fIARGS\fP]\fP
.SH "DESCRIPTION"
.sp
The specified target for the current package (or package specified by \fB\-p\fP if
provided) will be documented with the specified \fIARGS\fP being passed to the
final rustdoc invocation. Dependencies will not be documented as part of this
command. Note that rustdoc will still unconditionally receive arguments such
as \fB\-L\fP, \fB\-\-extern\fP, and \fB\-\-crate\-type\fP, and the specified \fIARGS\fP will simply
be added to the rustdoc invocation.
.sp
See \c
.URL "https://doc.rust\-lang.org/rustdoc/index.html" "" " "
for documentation on rustdoc
flags.
.sp
This command requires that only one target is being compiled when additional
arguments are provided. If more than one target is available for the current
package the filters of \fB\-\-lib\fP, \fB\-\-bin\fP, etc, must be used to select which
target is compiled.
To pass flags to all rustdoc processes spawned by Cargo, use the
\fBRUSTDOCFLAGS\fP environment variable or the \fBbuild.rustdocflags\fP configuration
option.
.SH "OPTIONS"
.SS "Documentation Options"
.sp
\fB\-\-open\fP
.RS 4
Open the docs in a browser after building them.
.RE
.SS "Package Selection"
.sp
By default, the package in the current working directory is selected. The \fB\-p\fP
flag can be used to choose a different package in a workspace.
.sp
\fB\-p\fP \fISPEC\fP, \fB\-\-package\fP \fISPEC\fP
.RS 4
The package to document. See \fBcargo\-pkgid\fP(1) for
the SPEC format.
.RE
.SS "Target Selection"
.sp
When no target selection options are given, \fBcargo rustdoc\fP will document all
binary and library targets of the selected package. The binary will be skipped
if its name is the same as the lib target. Binaries are skipped if they have
\fBrequired\-features\fP that are missing.
.sp
Passing target selection flags will document only the
specified targets.
.sp
\fB\-\-lib\fP
.RS 4
Document the package\(cqs library.
.RE
.sp
\fB\-\-bin\fP \fINAME\fP...
.RS 4
Document the specified binary. This flag may be specified multiple times.
.RE
.sp
\fB\-\-bins\fP
.RS 4
Document all binary targets.
.RE
.sp
\fB\-\-example\fP \fINAME\fP...
.RS 4
Document the specified example. This flag may be specified multiple times.
.RE
.sp
\fB\-\-examples\fP
.RS 4
Document all example targets.
.RE
.sp
\fB\-\-test\fP \fINAME\fP...
.RS 4
Document the specified integration test. This flag may be specified multiple
times.
.RE
.sp
\fB\-\-tests\fP
.RS 4
Document all targets in test mode that have the \fBtest = true\fP manifest
flag set. By default this includes the library and binaries built as
unittests, and integration tests. Be aware that this will also build any
required dependencies, so the lib target may be built twice (once as a
unittest, and once as a dependency for binaries, integration tests, etc.).
Targets may be enabled or disabled by setting the \fBtest\fP flag in the
manifest settings for the target.
.RE
.sp
\fB\-\-bench\fP \fINAME\fP...
.RS 4
Document the specified benchmark. This flag may be specified multiple times.
.RE
.sp
\fB\-\-benches\fP
.RS 4
Document all targets in benchmark mode that have the \fBbench = true\fP
manifest flag set. By default this includes the library and binaries built
as benchmarks, and bench targets. Be aware that this will also build any
required dependencies, so the lib target may be built twice (once as a
benchmark, and once as a dependency for binaries, benchmarks, etc.).
Targets may be enabled or disabled by setting the \fBbench\fP flag in the
manifest settings for the target.
.RE
.sp
\fB\-\-all\-targets\fP
.RS 4
Document all targets. This is equivalent to specifying \fB\-\-lib \-\-bins
\-\-tests \-\-benches \-\-examples\fP.
.RE
.SS "Feature Selection"
.sp
When no feature options are given, the \fBdefault\fP feature is activated for
every selected package.
.sp
\fB\-\-features\fP \fIFEATURES\fP
.RS 4
Space or comma separated list of features to activate. These features only
apply to the current directory\(cqs package. Features of direct dependencies
may be enabled with \fB<dep\-name>/<feature\-name>\fP syntax.
.RE
.sp
\fB\-\-all\-features\fP
.RS 4
Activate all available features of all selected packages.
.RE
.sp
\fB\-\-no\-default\-features\fP
.RS 4
Do not activate the \fBdefault\fP feature of the current directory\(cqs
package.
.RE
.SS "Compilation Options"
.sp
\fB\-\-target\fP \fITRIPLE\fP
.RS 4
Document 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
.sp
\fB\-\-release\fP
.RS 4
Document optimized artifacts with the \fBrelease\fP profile. See the
PROFILES section for details on how this affects profile selection.
.RE
.SS "Output Options"
.sp
\fB\-\-target\-dir\fP \fIDIRECTORY\fP
.RS 4
Directory for all generated artifacts and intermediate files. May also be
specified with the \fBCARGO_TARGET_DIR\fP environment variable, or the
\fBbuild.target\-dir\fP \c
.URL "https://doc.rust\-lang.org/cargo/reference/config.html" "config value" "."
Defaults
to \fBtarget\fP in the root of the workspace.
.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

.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.

.ie n \{\

.RE
.sp
\fB\-\-message\-format\fP \fIFMT\fP
.RS 4

.sp
.RS 4
.ie n \{\
\h'-04'\(bu\h'+03'\c
.\}
.el \{\
.  sp -1
.  IP \(bu 2.3

.ie n \{\
\h'-04'\(bu\h'+03'\c

.ie n \{\
\h'-04'\(bu\h'+03'\c

.el \{\

\fBshort\fP: Emit shorter, human\-readable text messages.
.RE
.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...

details.
.RE
.SS "Miscellaneous Options"
.sp
\fB\-j\fP \fIN\fP, \fB\-\-jobs\fP \fIN\fP
.RS 4
Number of parallel jobs to run. May also be specified with the
\fBbuild.jobs\fP \c
.URL "https://doc.rust\-lang.org/cargo/reference/config.html" "config value" "."
Defaults to
the number of CPUs.
.RE
.SH "PROFILES"
.sp
Profiles may be used to configure compiler options such as optimization levels
and debug settings. See
\c
.URL "https://doc.rust\-lang.org/cargo/reference/manifest.html#the\-profile\-sections" "the reference"
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.
