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 See <https://doc.rust-lang.org/rustdoc/index.html> for documentation on
21 rustdoc flags.
22 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 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.
40 Package Selection
42 By default, the package in the current working directory is selected.
43 The -p flag can be used to choose a different package in a workspace.
44 -p spec, --package spec
46 The package to document. See cargo-pkgid(1) for the SPEC format.
47 Target Selection
49 When no target selection options are given, cargo rustdoc will document
50 all binary and library targets of the selected package. The binary will
51 be skipped if its name is the same as the lib target. Binaries are
52 skipped if they have required-features that are missing.
53 Passing target selection flags will document only the specified
55 targets.
56 Note that --bin, --example, --test and --bench flags also support
58 common Unix glob patterns like *, ? and []. However, to avoid your
59 shell accidentally expanding glob patterns before Cargo handles them,
60 you must use single quotes or double quotes around each glob pattern.
61 --lib
63 Document the package's library.
64 --bin name...
66 Document the specified binary. This flag may be specified multiple
67 times and supports common Unix glob patterns.
68 --bins
70 Document all binary targets.
71 --example name...
73 Document the specified example. This flag may be specified multiple
74 times and supports common Unix glob patterns.
75 --examples
77 Document all example targets.
78 --test name...
80 Document the specified integration test. This flag may be specified
81 multiple times and supports common Unix glob patterns.
82 --tests
84 Document all targets in test mode that have the test = true
85 manifest flag set. By default this includes the library and
86 binaries built as unittests, and integration tests. Be aware that
87 this will also build any required dependencies, so the lib target
88 may be built twice (once as a unittest, and once as a dependency
89 for binaries, integration tests, etc.). Targets may be enabled or
90 disabled by setting the test flag in the manifest settings for the
91 target.
92 --bench name...
94 Document the specified benchmark. This flag may be specified
95 multiple times and supports common Unix glob patterns.
96 --benches
98 Document all targets in benchmark mode that have the bench = true
99 manifest flag set. By default this includes the library and
100 binaries built as benchmarks, and bench targets. Be aware that this
101 will also build any required dependencies, so the lib target may be
102 built twice (once as a benchmark, and once as a dependency for
103 binaries, benchmarks, etc.). Targets may be enabled or disabled by
104 setting the bench flag in the manifest settings for the target.
105 --all-targets
107 Document all targets. This is equivalent to specifying --lib --bins
108 --tests --benches --examples.
109 Feature Selection
111 The feature flags allow you to control which features are enabled. When
112 no feature options are given, the default feature is activated for
113 every selected package.
114 See the features documentation
116 <https://doc.rust-lang.org/cargo/reference/features.html#command-line-feature-options>
117 for more details.
118 --features features
120 Space or comma separated list of features to activate. Features of
121 workspace members may be enabled with package-name/feature-name
122 syntax. This flag may be specified multiple times, which enables
123 all specified features.
124 --all-features
126 Activate all available features of all selected packages.
127 --no-default-features
129 Do not activate the default feature of the selected packages.
130 Compilation Options
132 --target triple
133 Document for the given architecture. The default is the host
134 architecture. The general format of the triple is
135 <arch><sub>-<vendor>-<sys>-<abi>. Run rustc --print target-list for
136 a list of supported targets.
137 This may also be specified with the build.target config value
139 <https://doc.rust-lang.org/cargo/reference/config.html>.
140 Note that specifying this flag makes Cargo run in a different mode
142 where the target artifacts are placed in a separate directory. See
143 the build cache
144 <https://doc.rust-lang.org/cargo/guide/build-cache.html>
145 documentation for more details.
146 --release
148 Document optimized artifacts with the release profile. See the
149 PROFILES section for details on how this affects profile selection.
150 Output Options
152 --target-dir directory
153 Directory for all generated artifacts and intermediate files. May
154 also be specified with the CARGO_TARGET_DIR environment variable,
155 or the build.target-dir config value
156 <https://doc.rust-lang.org/cargo/reference/config.html>. Defaults
157 to target in the root of the workspace.
158 Display Options
160 -v, --verbose
161 Use verbose output. May be specified twice for "very verbose"
162 output which includes extra output such as dependency warnings and
163 build script output. May also be specified with the term.verbose
164 config value
165 <https://doc.rust-lang.org/cargo/reference/config.html>.
166 -q, --quiet
168 No output printed to stdout.
169 --color when
171 Control when colored output is used. Valid values:
172 · auto (default): Automatically detect if color support is
174 available on the terminal.
175 · always: Always display colors.
177 · never: Never display colors.
179 May also be specified with the term.color config value
181 <https://doc.rust-lang.org/cargo/reference/config.html>.
182 --message-format fmt
184 The output format for diagnostic messages. Can be specified
185 multiple times and consists of comma-separated values. Valid
186 values:
187 · human (default): Display in a human-readable text format.
189 · short: Emit shorter, human-readable text messages.
191 · json: Emit JSON messages to stdout. See the reference
193 <https://doc.rust-lang.org/cargo/reference/external-tools.html#json-messages>
194 for more details.
195 · json-diagnostic-short: Ensure the rendered field of JSON
197 messages contains the "short" rendering from rustc.
198 · json-diagnostic-rendered-ansi: Ensure the rendered field of JSON
200 messages contains embedded ANSI color codes for respecting
201 rustc's default color scheme.
202 · json-render-diagnostics: Instruct Cargo to not include rustc
204 diagnostics in in JSON messages printed, but instead Cargo
205 itself should render the JSON diagnostics coming from rustc.
206 Cargo's own JSON diagnostics and others coming from rustc are
207 still emitted.
208 Manifest Options
210 --manifest-path path
211 Path to the Cargo.toml file. By default, Cargo searches for the
212 Cargo.toml file in the current directory or any parent directory.
213 --frozen, --locked
215 Either of these flags requires that the Cargo.lock file is
216 up-to-date. If the lock file is missing, or it needs to be updated,
217 Cargo will exit with an error. The --frozen flag also prevents
218 Cargo from attempting to access the network to determine if it is
219 out-of-date.
220 These may be used in environments where you want to assert that the
222 Cargo.lock file is up-to-date (such as a CI build) or want to avoid
223 network access.
224 --offline
226 Prevents Cargo from accessing the network for any reason. Without
227 this flag, Cargo will stop with an error if it needs to access the
228 network and the network is not available. With this flag, Cargo
229 will attempt to proceed without the network if possible.
230 Beware that this may result in different dependency resolution than
232 online mode. Cargo will restrict itself to crates that are
233 downloaded locally, even if there might be a newer version as
234 indicated in the local copy of the index. See the cargo-fetch(1)
235 command to download dependencies before going offline.
236 May also be specified with the net.offline config value
238 <https://doc.rust-lang.org/cargo/reference/config.html>.
239 Common Options
241 +toolchain
242 If Cargo has been installed with rustup, and the first argument to
243 cargo begins with +, it will be interpreted as a rustup toolchain
244 name (such as +stable or +nightly). See the rustup documentation
245 <https://rust-lang.github.io/rustup/overrides.html> for more
246 information about how toolchain overrides work.
247 -h, --help
249 Prints help information.
250 -Z flag
252 Unstable (nightly-only) flags to Cargo. Run cargo -Z help for
253 details.
254 Miscellaneous Options
256 -j N, --jobs N
257 Number of parallel jobs to run. May also be specified with the
258 build.jobs config value
259 <https://doc.rust-lang.org/cargo/reference/config.html>. Defaults
260 to the number of CPUs.
261
263 Profiles may be used to configure compiler options such as optimization
264 levels and debug settings. See the reference
265 <https://doc.rust-lang.org/cargo/reference/profiles.html> for more
266 details.
267 Profile selection depends on the target and crate being built. By
269 default the dev or test profiles are used. If the --release flag is
270 given, then the release or bench profiles are used.
271 ┌────────────────────┬─────────────────┬───────────────────┐
274 │Target │ Default Profile │ --release Profile │
275 ├────────────────────┼─────────────────┼───────────────────┤
276 │lib, bin, example │ dev │ release │
277 ├────────────────────┼─────────────────┼───────────────────┤
278 │test, bench, or any │ test │ bench │
279 │target in "test" or │ │ │
280 │"bench" mode │ │ │
281 └────────────────────┴─────────────────┴───────────────────┘
282 Dependencies use the dev/release profiles.
