PackageSelection
By default, the package in the current working directory is selected. The -p flag can be used to choose a
different package in a workspace.
-pspec, --packagespec
The package to run. See cargo-pkgid(1) for the SPEC format.
TargetSelection
When no target selection options are given, cargorun will run the binary target. If there are multiple
binary targets, you must pass a target flag to choose one. Or, the default-run field may be specified in
the [package] section of Cargo.toml to choose the name of the binary to run by default.
--binname
Run the specified binary.
--examplename
Run the specified example.
FeatureSelection
The feature flags allow you to control which features are enabled. When no feature options are given, the
default feature is activated for every selected package.
See thefeaturesdocumentation
<https://doc.rust-lang.org/cargo/reference/features.html#command-line-feature-options> for more details.
-Ffeatures, --featuresfeatures
Space or comma separated list of features to activate. Features of workspace members may be enabled
with package-name/feature-name syntax. This flag may be specified multiple times, which enables all
specified features.
--all-features
Activate all available features of all selected packages.
--no-default-features
Do not activate the default feature of the selected packages.
CompilationOptions--targettriple
Run for the given architecture. The default is the host architecture. The general format of the
triple is <arch><sub>-<vendor>-<sys>-<abi>. Run rustc--printtarget-list for a list of supported
targets.
This may also be specified with the build.targetconfigvalue
<https://doc.rust-lang.org/cargo/reference/config.html>.
Note that specifying this flag makes Cargo run in a different mode where the target artifacts are
placed in a separate directory. See the buildcache
<https://doc.rust-lang.org/cargo/reference/build-cache.html> documentation for more details.
-r, --release
Run optimized artifacts with the release profile. See also the --profile option for choosing a
specific profile by name.
--profilename
Run with the given profile. See thereference
<https://doc.rust-lang.org/cargo/reference/profiles.html> for more details on profiles.
--timings=fmts
Output information how long each compilation takes, and track concurrency information over time.
Accepts an optional comma-separated list of output formats; --timings without an argument will
default to --timings=html. Specifying an output format (rather than the default) is unstable and
requires -Zunstable-options. Valid output formats:
• html (unstable, requires -Zunstable-options): Write a human-readable file cargo-timing.html to the
target/cargo-timings directory with a report of the compilation. Also write a report to the same
directory with a timestamp in the filename if you want to look at older runs. HTML output is
suitable for human consumption only, and does not provide machine-readable timing data.
• json (unstable, requires -Zunstable-options): Emit machine-readable JSON information about timing
information.
OutputOptions--target-dirdirectory
Directory for all generated artifacts and intermediate files. May also be specified with the
CARGO_TARGET_DIR environment variable, or the build.target-dirconfigvalue
<https://doc.rust-lang.org/cargo/reference/config.html>. Defaults to target in the root of the
workspace.
DisplayOptions-v, --verbose
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 term.verboseconfigvalue <https://doc.rust-lang.org/cargo/reference/config.html>.
-q, --quiet
Do not print cargo log messages. May also be specified with the term.quietconfigvalue
<https://doc.rust-lang.org/cargo/reference/config.html>.
--colorwhen
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 term.colorconfigvalue
<https://doc.rust-lang.org/cargo/reference/config.html>.
--message-formatfmt
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. Conflicts with short and json.
• short: Emit shorter, human-readable text messages. Conflicts with human and json.
• json: Emit JSON messages to stdout. See thereference
<https://doc.rust-lang.org/cargo/reference/external-tools.html#json-messages> for more details.
Conflicts with human and short.
• json-diagnostic-short: Ensure the rendered field of JSON messages contains the “short” rendering
from rustc. Cannot be used with human or short.
• json-diagnostic-rendered-ansi: Ensure the rendered field of JSON messages contains embedded ANSI
color codes for respecting rustc’s default color scheme. Cannot be used with human or short.
• json-render-diagnostics: Instruct Cargo to not include rustc diagnostics 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. Cannot be used with human or short.
ManifestOptions--manifest-pathpath
Path to the Cargo.toml file. By default, Cargo searches for the Cargo.toml file in the current
directory or any parent directory.
--ignore-rust-version
Ignore rust-version specification in packages.
--locked
Asserts that the exact same dependencies and versions are used as when the existing Cargo.lock file
was originally generated. Cargo will exit with an error when either of the following scenarios
arises:
• The lock file is missing.
• Cargo attempted to change the lock file due to a different dependency resolution.
It may be used in environments where deterministic builds are desired, such as in CI pipelines.
--offline
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 net.offlineconfigvalue
<https://doc.rust-lang.org/cargo/reference/config.html>.
--frozen
Equivalent to specifying both --locked and --offline.
--lockfile-pathPATH
Changes the path of the lockfile from the default (<workspace_root>/Cargo.lock) to PATH. PATH must
end with Cargo.lock (e.g. --lockfile-path/tmp/temporary-lockfile/Cargo.lock). Note that providing
--lockfile-path will ignore existing lockfile at the default path, and instead will either use the
lockfile from PATH, or write a new lockfile into the provided PATH if it doesn’t exist. This flag can
be used to run most commands in read-only directories, writing lockfile into the provided PATH.
This option is only available on the nightlychannel
<https://doc.rust-lang.org/book/appendix-07-nightly-rust.html> and requires the -Zunstable-options
flag to enable (see #14421 <https://github.com/rust-lang/cargo/issues/14421>).
CommonOptions+toolchain
If Cargo has been installed with rustup, and the first argument to cargo begins with +, it will be
interpreted as a rustup toolchain name (such as +stable or +nightly). See the rustupdocumentation
<https://rust-lang.github.io/rustup/overrides.html> for more information about how toolchain
overrides work.
--configKEY=VALUE or PATH
Overrides a Cargo configuration value. The argument should be in TOML syntax of KEY=VALUE, or
provided as a path to an extra configuration file. This flag may be specified multiple times. See the
command-lineoverridessection
<https://doc.rust-lang.org/cargo/reference/config.html#command-line-overrides> for more information.
-CPATH
Changes the current working directory before executing any specified operations. This affects things
like where cargo looks by default for the project manifest (Cargo.toml), as well as the directories
searched for discovering .cargo/config.toml, for example. This option must appear before the command
name, for example cargo-Cpath/to/my-projectbuild.
This option is only available on the nightlychannel
<https://doc.rust-lang.org/book/appendix-07-nightly-rust.html> and requires the -Zunstable-options
flag to enable (see #10098 <https://github.com/rust-lang/cargo/issues/10098>).
-h, --help
Prints help information.
-Zflag
Unstable (nightly-only) flags to Cargo. Run cargo-Zhelp for details.
MiscellaneousOptions-jN, --jobsN
Number of parallel jobs to run. May also be specified with the build.jobsconfigvalue
<https://doc.rust-lang.org/cargo/reference/config.html>. Defaults to the number of logical CPUs. If
negative, it sets the maximum number of parallel jobs to the number of logical CPUs plus provided
value. If a string default is provided, it sets the value back to defaults. Should not be 0.
--keep-going
Build as many crates in the dependency graph as possible, rather than aborting the build on the first
one that fails to build.
For example if the current package depends on dependencies fails and works, one of which fails to
build, cargorun-j1 may or may not build the one that succeeds (depending on which one of the two
builds Cargo picked to run first), whereas cargorun-j1--keep-going would definitely run both
builds, even if the one run first fails.
