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. To pass flags to all rustdoc
27 processes spawned by Cargo, use the RUSTDOCFLAGS environment variable
28 or the build.rustdocflags configuration option.
29
31 Documentation Options
32 --open
33 Open the docs in a browser after building them.
34 Package Selection
36 By default, the package in the current working directory is selected.
37 The -p flag can be used to choose a different package in a workspace.
38 -p SPEC, --package SPEC
40 The package to document. See cargo-pkgid(1) for the SPEC format.
41 Target Selection
43 When no target selection options are given, cargo rustdoc will document
44 all binary and library targets of the selected package. The binary will
45 be skipped if its name is the same as the lib target. Binaries are
46 skipped if they have required-features that are missing.
47 Passing target selection flags will document only the specified
49 targets.
50 --lib
52 Document the package’s library.
53 --bin NAME...
55 Document the specified binary. This flag may be specified multiple
56 times.
57 --bins
59 Document all binary targets.
60 --example NAME...
62 Document the specified example. This flag may be specified multiple
63 times.
64 --examples
66 Document all example targets.
67 --test NAME...
69 Document the specified integration test. This flag may be specified
70 multiple times.
71 --tests
73 Document all targets in test mode that have the test = true
74 manifest flag set. By default this includes the library and
75 binaries built as unittests, and integration tests. Be aware that
76 this will also build any required dependencies, so the lib target
77 may be built twice (once as a unittest, and once as a dependency
78 for binaries, integration tests, etc.). Targets may be enabled or
79 disabled by setting the test flag in the manifest settings for the
80 target.
81 --bench NAME...
83 Document the specified benchmark. This flag may be specified
84 multiple times.
85 --benches
87 Document all targets in benchmark mode that have the bench = true
88 manifest flag set. By default this includes the library and
89 binaries built as benchmarks, and bench targets. Be aware that this
90 will also build any required dependencies, so the lib target may be
91 built twice (once as a benchmark, and once as a dependency for
92 binaries, benchmarks, etc.). Targets may be enabled or disabled by
93 setting the bench flag in the manifest settings for the target.
94 --all-targets
96 Document all targets. This is equivalent to specifying --lib --bins
97 --tests --benches --examples.
98 Feature Selection
100 When no feature options are given, the default feature is activated for
101 every selected package.
102 --features FEATURES
104 Space or comma separated list of features to activate. These
105 features only apply to the current directory’s package. Features of
106 direct dependencies may be enabled with <dep-name>/<feature-name>
107 syntax.
108 --all-features
110 Activate all available features of all selected packages.
111 --no-default-features
113 Do not activate the default feature of the current directory’s
114 package.
115 Compilation Options
117 --target TRIPLE
118 Document for the given architecture. The default is the host
119 architecture. The general format of the triple is
120 <arch><sub>-<vendor>-<sys>-<abi>. Run rustc --print target-list for
121 a list of supported targets.
122 This may also be specified with the build.target config value
124 <https://doc.rust-lang.org/cargo/reference/config.html>.
125 --release
127 Document optimized artifacts with the release profile. See the
128 PROFILES section for details on how this affects profile selection.
129 Output Options
131 --target-dir DIRECTORY
132 Directory for all generated artifacts and intermediate files. May
133 also be specified with the CARGO_TARGET_DIR environment variable,
134 or the build.target-dir config value
135 <https://doc.rust-lang.org/cargo/reference/config.html>. Defaults
136 to target in the root of the workspace.
137 Display Options
139 -v, --verbose
140 Use verbose output. May be specified twice for "very verbose"
141 output which includes extra output such as dependency warnings and
142 build script output. May also be specified with the term.verbose
143 config value
144 <https://doc.rust-lang.org/cargo/reference/config.html>.
145 -q, --quiet
147 No output printed to stdout.
148 --color WHEN
150 Control when colored output is used. Valid values:
151 · auto (default): Automatically detect if color support is
153 available on the terminal.
154 · always: Always display colors.
156 · never: Never display colors.
158 May also be specified with the term.color config value
160 <https://doc.rust-lang.org/cargo/reference/config.html>.
161 --message-format FMT
163 The output format for diagnostic messages. Valid values:
164 · human (default): Display in a human-readable text format.
166 · json: Emit JSON messages to stdout.
168 · short: Emit shorter, human-readable text messages.
170 Manifest Options
172 --manifest-path PATH
173 Path to the Cargo.toml file. By default, Cargo searches in the
174 current directory or any parent directory for the Cargo.toml file.
175 --frozen, --locked
177 Either of these flags requires that the Cargo.lock file is
178 up-to-date. If the lock file is missing, or it needs to be updated,
179 Cargo will exit with an error. The --frozen flag also prevents
180 Cargo from attempting to access the network to determine if it is
181 out-of-date.
182 These may be used in environments where you want to assert that the
184 Cargo.lock file is up-to-date (such as a CI build) or want to avoid
185 network access.
186 Common Options
188 -h, --help
189 Prints help information.
190 -Z FLAG...
192 Unstable (nightly-only) flags to Cargo. Run cargo -Z help for
193 details.
194 Miscellaneous Options
196 -j N, --jobs N
197 Number of parallel jobs to run. May also be specified with the
198 build.jobs config value
199 <https://doc.rust-lang.org/cargo/reference/config.html>. Defaults
200 to the number of CPUs.
201
203 Profiles may be used to configure compiler options such as optimization
204 levels and debug settings. See the reference
205 <https://doc.rust-lang.org/cargo/reference/manifest.html#the-profile-sections>
206 for more details.
207 Profile selection depends on the target and crate being built. By
209 default the dev or test profiles are used. If the --release flag is
210 given, then the release or bench profiles are used.
