cargo-rustdoc - Build a package's documentation, using specified custom flags
cargo rustdoc [options] [
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.
- Open the docs in a browser after building them. This will use your default
browser unless you define another one in the
By default, the package in the current working directory is selected. The
flag can be used to choose a different package in a workspace.
- 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.
--bench flags also
support common Unix glob patterns like
. However, to avoid your
shell accidentally expanding glob patterns before Cargo handles them, you must
use single quotes or double quotes around each glob pattern.
- Document the package's library.
- Document the specified binary. This flag may be specified multiple times and supports common Unix glob patterns.
- Document all binary targets.
- Document the specified example. This flag may be specified multiple times and supports common Unix glob patterns.
- Document all example targets.
- Document the specified integration test. This flag may be specified multiple times and supports common Unix glob patterns.
- 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.
- Document the specified benchmark. This flag may be specified multiple times and supports common Unix glob patterns.
- 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.
The feature flags allow you to control the enabled features for the "current"
package. The "current" package is the package in the current directory, or the
one specified in
--manifest-path. If running in the root of a virtual
workspace, then the default features are selected for all workspace members,
or all features if
--all-features is specified.
When no feature options are given, the
default feature is activated for
every selected package.
- 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
<dep-name>/<feature-name>syntax. This flag may be specified multiple times, which enables all specified features.
- Activate all available features of all selected packages.
- Do not activate the
defaultfeature of the current directory's package.
- 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
Note that specifying this flag makes Cargo run in a different mode where the target artifacts are placed in a separate directory. See the build cache documentation for more details.
- Document optimized artifacts with the
releaseprofile. See the PROFILES section for details on how this affects profile selection.
- 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.
- 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
- The output format for diagnostic messages. Can be specified multiple times
and consists of comma-separated values. Valid values:
human(default): Display in a human-readable text format.
short: Emit shorter, human-readable text messages.
json: Emit JSON messages to stdout. See the reference for more details.
json-diagnostic-short: Ensure the
renderedfield of JSON messages contains the "short" rendering from rustc.
json-diagnostic-rendered-ansi: Ensure the
renderedfield of JSON messages contains embedded ANSI color codes for respecting rustc's default color scheme.
json-render-diagnostics: Instruct Cargo to not include rustc diagnostics in in JSON messages printed, but instead Cargo itself should render the JSON diagnostics coming from rustc. Cargo's own JSON diagnostics and others coming from rustc are still emitted.
- Path to the
Cargo.tomlfile. By default, Cargo searches for the
Cargo.tomlfile in the current directory or any parent directory.
- 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.
- Prevents Cargo from accessing the network for any reason. Without this
flag, Cargo will stop with an error if it needs to access the network and
the network is not available. With this flag, Cargo will attempt to
proceed without the network if possible.
Beware that this may result in different dependency resolution than online mode. Cargo will restrict itself to crates that are downloaded locally, even if there might be a newer version as indicated in the local copy of the index. See the cargo-fetch(1) command to download dependencies before going offline.
May also be specified with the
- If Cargo has been installed with rustup, and the first argument to
+, it will be interpreted as a rustup toolchain name (such as
+nightly). See the rustup documentation for more information about how toolchain overrides work.
- Prints help information.
- Unstable (nightly-only) flags to Cargo. Run
cargo -Z helpfor details.
- 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.
