6 cargo-rustdoc - Build a package's documentation, using specified custom
7 flags
8
10 cargo rustdoc [options] [-- args]
11
13 The specified target for the current package (or package specified by
14 -p if provided) will be documented with the specified args being passed
15 to the final rustdoc invocation. Dependencies will not be documented as
16 part of this command. Note that rustdoc will still unconditionally
17 receive arguments such as -L, --extern, and --crate-type, and the
18 specified args will simply be added to the rustdoc invocation.
19
20 See <https://doc.rust-lang.org/rustdoc/index.html> for documentation on
21 rustdoc flags.
22
23 This command requires that only one target is being compiled when
24 additional arguments are provided. If more than one target is available
25 for the current package the filters of --lib, --bin, etc, must be used
26 to select which target is compiled.
27
28 To pass flags to all rustdoc processes spawned by Cargo, use the
29 RUSTDOCFLAGS environment variable
30 <https://doc.rust-lang.org/cargo/reference/environment-variables.html>
31 or the build.rustdocflags config value
32 <https://doc.rust-lang.org/cargo/reference/config.html>.
33
35 Documentation Options
36 --open
37 Open the docs in a browser after building them. This will use your
38 default browser unless you define another one in the BROWSER
39 environment variable or use the doc.browser
40 <https://doc.rust-lang.org/cargo/reference/config.html#docbrowser>
41 configuration option.
42
43 Package Selection
44 By default, the package in the current working directory is selected.
45 The -p flag can be used to choose a different package in a workspace.
46
47 -p spec, --package spec
48 The package to document. See cargo-pkgid(1) for the SPEC format.
49
50 Target Selection
51 When no target selection options are given, cargo rustdoc will document
52 all binary and library targets of the selected package. The binary will
53 be skipped if its name is the same as the lib target. Binaries are
54 skipped if they have required-features that are missing.
55
56 Passing target selection flags will document only the specified
57 targets.
58
59 Note that --bin, --example, --test and --bench flags also support
60 common Unix glob patterns like *, ? and []. However, to avoid your
61 shell accidentally expanding glob patterns before Cargo handles them,
62 you must use single quotes or double quotes around each glob pattern.
63
64 --lib
65 Document the package's library.
66
67 --bin name...
68 Document the specified binary. This flag may be specified multiple
69 times and supports common Unix glob patterns.
70
71 --bins
72 Document all binary targets.
73
74 --example name...
75 Document the specified example. This flag may be specified multiple
76 times and supports common Unix glob patterns.
77
78 --examples
79 Document all example targets.
80
81 --test name...
82 Document the specified integration test. This flag may be specified
83 multiple times and supports common Unix glob patterns.
84
85 --tests
86 Document all targets in test mode that have the test = true
87 manifest flag set. By default this includes the library and
88 binaries built as unittests, and integration tests. Be aware that
89 this will also build any required dependencies, so the lib target
90 may be built twice (once as a unittest, and once as a dependency
91 for binaries, integration tests, etc.). Targets may be enabled or
92 disabled by setting the test flag in the manifest settings for the
93 target.
94
95 --bench name...
96 Document the specified benchmark. This flag may be specified
97 multiple times and supports common Unix glob patterns.
98
99 --benches
100 Document all targets in benchmark mode that have the bench = true
101 manifest flag set. By default this includes the library and
102 binaries built as benchmarks, and bench targets. Be aware that this
103 will also build any required dependencies, so the lib target may be
104 built twice (once as a benchmark, and once as a dependency for
105 binaries, benchmarks, etc.). Targets may be enabled or disabled by
106 setting the bench flag in the manifest settings for the target.
107
108 --all-targets
109 Document all targets. This is equivalent to specifying --lib --bins
110 --tests --benches --examples.
111
112 Feature Selection
113 The feature flags allow you to control which features are enabled. When
114 no feature options are given, the default feature is activated for
115 every selected package.
116
117 See the features documentation
118 <https://doc.rust-lang.org/cargo/reference/features.html#command-line-feature-options>
119 for more details.
120
121 -F features, --features features
122 Space or comma separated list of features to activate. Features of
123 workspace members may be enabled with package-name/feature-name
124 syntax. This flag may be specified multiple times, which enables
125 all specified features.
126
127 --all-features
128 Activate all available features of all selected packages.
129
130 --no-default-features
131 Do not activate the default feature of the selected packages.
132
133 Compilation Options
134 --target triple
135 Document for the given architecture. The default is the host
136 architecture. The general format of the triple is
137 <arch><sub>-<vendor>-<sys>-<abi>. Run rustc --print target-list for
138 a list of supported targets.
139
140 This may also be specified with the build.target config value
141 <https://doc.rust-lang.org/cargo/reference/config.html>.
142
143 Note that specifying this flag makes Cargo run in a different mode
144 where the target artifacts are placed in a separate directory. See
145 the build cache
146 <https://doc.rust-lang.org/cargo/guide/build-cache.html>
147 documentation for more details.
148
149 -r, --release
150 Document optimized artifacts with the release profile. See also the
151 --profile option for choosing a specific profile by name.
152
153 --profile name
154 Document with the given profile. See the the reference
155 <https://doc.rust-lang.org/cargo/reference/profiles.html> for more
156 details on profiles.
157
158 --ignore-rust-version
159 Document the target even if the selected Rust compiler is older
160 than the required Rust version as configured in the project's
161 rust-version field.
162
163 --timings=fmts
164 Output information how long each compilation takes, and track
165 concurrency information over time. Accepts an optional
166 comma-separated list of output formats; --timings without an
167 argument will default to --timings=html. Specifying an output
168 format (rather than the default) is unstable and requires
169 -Zunstable-options. Valid output formats:
170
171 • html: Write a human-readable file cargo-timing.html to the
172 target/cargo-timings directory with a report of the
173 compilation. Also write a report to the same directory with a
174 timestamp in the filename if you want to look at older runs.
175 HTML output is suitable for human consumption only, and does
176 not provide machine-readable timing data.
177
178 • json (unstable, requires -Zunstable-options): Emit
179 machine-readable JSON information about timing information.
180
181 Output Options
182 --target-dir directory
183 Directory for all generated artifacts and intermediate files. May
184 also be specified with the CARGO_TARGET_DIR environment variable,
185 or the build.target-dir config value
186 <https://doc.rust-lang.org/cargo/reference/config.html>. Defaults
187 to target in the root of the workspace.
188
189 Display Options
190 -v, --verbose
191 Use verbose output. May be specified twice for "very verbose"
192 output which includes extra output such as dependency warnings and
193 build script output. May also be specified with the term.verbose
194 config value
195 <https://doc.rust-lang.org/cargo/reference/config.html>.
196
197 -q, --quiet
198 Do not print cargo log messages. May also be specified with the
199 term.quiet config value
200 <https://doc.rust-lang.org/cargo/reference/config.html>.
201
202 --color when
203 Control when colored output is used. Valid values:
204
205 • auto (default): Automatically detect if color support is
206 available on the terminal.
207
208 • always: Always display colors.
209
210 • never: Never display colors.
211
212 May also be specified with the term.color config value
213 <https://doc.rust-lang.org/cargo/reference/config.html>.
214
215 --message-format fmt
216 The output format for diagnostic messages. Can be specified
217 multiple times and consists of comma-separated values. Valid
218 values:
219
220 • human (default): Display in a human-readable text format.
221 Conflicts with short and json.
222
223 • short: Emit shorter, human-readable text messages. Conflicts
224 with human and json.
225
226 • json: Emit JSON messages to stdout. See the reference
227 <https://doc.rust-lang.org/cargo/reference/external-tools.html#json-messages>
228 for more details. Conflicts with human and short.
229
230 • json-diagnostic-short: Ensure the rendered field of JSON
231 messages contains the "short" rendering from rustc. Cannot be
232 used with human or short.
233
234 • json-diagnostic-rendered-ansi: Ensure the rendered field of JSON
235 messages contains embedded ANSI color codes for respecting
236 rustc's default color scheme. Cannot be used with human or
237 short.
238
239 • json-render-diagnostics: Instruct Cargo to not include rustc
240 diagnostics in in JSON messages printed, but instead Cargo
241 itself should render the JSON diagnostics coming from rustc.
242 Cargo's own JSON diagnostics and others coming from rustc are
243 still emitted. Cannot be used with human or short.
244
245 Manifest Options
246 --manifest-path path
247 Path to the Cargo.toml file. By default, Cargo searches for the
248 Cargo.toml file in the current directory or any parent directory.
249
250 --frozen, --locked
251 Either of these flags requires that the Cargo.lock file is
252 up-to-date. If the lock file is missing, or it needs to be updated,
253 Cargo will exit with an error. The --frozen flag also prevents
254 Cargo from attempting to access the network to determine if it is
255 out-of-date.
256
257 These may be used in environments where you want to assert that the
258 Cargo.lock file is up-to-date (such as a CI build) or want to avoid
259 network access.
260
261 --offline
262 Prevents Cargo from accessing the network for any reason. Without
263 this flag, Cargo will stop with an error if it needs to access the
264 network and the network is not available. With this flag, Cargo
265 will attempt to proceed without the network if possible.
266
267 Beware that this may result in different dependency resolution than
268 online mode. Cargo will restrict itself to crates that are
269 downloaded locally, even if there might be a newer version as
270 indicated in the local copy of the index. See the cargo-fetch(1)
271 command to download dependencies before going offline.
272
273 May also be specified with the net.offline config value
274 <https://doc.rust-lang.org/cargo/reference/config.html>.
275
276 Common Options
277 +toolchain
278 If Cargo has been installed with rustup, and the first argument to
279 cargo begins with +, it will be interpreted as a rustup toolchain
280 name (such as +stable or +nightly). See the rustup documentation
281 <https://rust-lang.github.io/rustup/overrides.html> for more
282 information about how toolchain overrides work.
283
284 -h, --help
285 Prints help information.
286
287 -Z flag
288 Unstable (nightly-only) flags to Cargo. Run cargo -Z help for
289 details.
290
291 Miscellaneous Options
292 -j N, --jobs N
293 Number of parallel jobs to run. May also be specified with the
294 build.jobs config value
295 <https://doc.rust-lang.org/cargo/reference/config.html>. Defaults
296 to the number of CPUs.
297
298 --keep-going
299 Build as many crates in the dependency graph as possible, rather
300 than aborting the build on the first one that fails to build.
301 Unstable, requires -Zunstable-options.
302
304 See the reference
305 <https://doc.rust-lang.org/cargo/reference/environment-variables.html>
306 for details on environment variables that Cargo reads.
