cargo-rustdoc - Build a package's documentation, using specified custom flags
cargo rustdoc [OPTIONS] [-- ARGS]
The specified target for the current package (or package specified by
provided) will be documented with the specified ARGS 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
--crate-type, and the specified ARGS will simply
be added to the rustdoc invocation.
See https://doc.rust-lang.org/rustdoc/index.html for documentation on rustdoc flags.
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
--bin, etc, must be used to select which
target is compiled.
To pass flags to all rustdoc processes spawned by Cargo, use the
RUSTDOCFLAGS environment variable or the
Open the docs in a browser after building them.
By default, the package in the current working directory is selected. The
flag can be used to choose a different package in a workspace.
- -p SPEC
- --package SPEC
The package to document. See cargo-pkgid(1) for the SPEC format.
When no target selection options are given,
cargo rustdoc 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
required-features that are missing.
Passing target selection flags will document only the specified targets.
Document the package’s library.
- --bin NAME…
Document the specified binary. This flag may be specified multiple times.
Document all binary targets.
- --example NAME…
Document the specified example. This flag may be specified multiple times.
Document all example targets.
- --test NAME…
Document the specified integration test. This flag may be specified multiple times.
Document all targets in test mode that have the
test = truemanifest 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
testflag in the manifest settings for the target.
- --bench NAME…
Document the specified benchmark. This flag may be specified multiple times.
Document all targets in benchmark mode that have the
bench = truemanifest 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
benchflag in the manifest settings for the target.
Document all targets. This is equivalent to specifying
--lib --bins --tests --benches --examples.
When no feature options are given, the
default feature is activated for
every selected package.
- --features FEATURES
Space or comma separated list of features to activate. These features only apply to the current directory’s package. Features of direct dependencies may be enabled with
Activate all available features of all selected packages.
Do not activate the
defaultfeature of the current directory’s package.
- --target TRIPLE
Document for the given architecture. The default is the host architecture. The general format of the triple is
rustc --print target-listfor a list of supported targets.
This may also be specified with the
Document optimized artifacts with the
releaseprofile. See the PROFILES section for details on how this affects profile selection.
- --target-dir DIRECTORY
Directory for all generated artifacts and intermediate files. May also be specified with the
CARGO_TARGET_DIRenvironment variable, or the
build.target-dirconfig value. Defaults to
targetin the root of the workspace.
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
No output printed to stdout.
- --color WHEN
Control when colored output is used. Valid values:
auto(default): Automatically detect if color support is available on the terminal.
always: Always display colors.
never: Never display colors.
May also be specified with the
- --message-format FMT
The output format for diagnostic messages. Valid values:
human(default): Display in a human-readable text format.
json: Emit JSON messages to stdout.
short: Emit shorter, human-readable text messages.
- --manifest-path PATH
Path to the
Cargo.tomlfile. By default, Cargo searches in the current directory or any parent directory for the
Either of these flags requires that the
Cargo.lockfile is up-to-date. If the lock file is missing, or it needs to be updated, Cargo will exit with an error. The
--frozenflag also prevents Cargo from attempting to access the network to determine if it is out-of-date.
These may be used in environments where you want to assert that the
Cargo.lockfile is up-to-date (such as a CI build) or want to avoid network access.
Prints help information.
- -Z FLAG…
Unstable (nightly-only) flags to Cargo. Run
cargo -Z helpfor details.
- -j N
- --jobs N
Number of parallel jobs to run. May also be specified with the
build.jobsconfig value. Defaults to the number of CPUs.
Profiles may be used to configure compiler options such as optimization levels and debug settings. See the reference for more details.
Profile selection depends on the target and crate being built. By default the
test profiles are used. If the
--release flag is given, then the
bench profiles are used.
