cargo-run — Run the current package

Description

       Run a binary or example of the local package.

       All the arguments following the two dashes (--) are passed to the binary to run. If you’re passing
       arguments to both Cargo and the binary, the ones after -- go to the binary, the ones before go to Cargo.

       Unlike cargo-test(1) and cargo-bench(1), cargorun sets the working directory of the binary executed to
       the current working directory, same as if it was executed in the shell directly.

Environment

       See thereference <https://doc.rust-lang.org/cargo/reference/environment-variables.html> for details on
       environment variables that Cargo reads.

Examples

        1. Build the local package and run its main target (assuming only one binary):

               cargo run

        2. Run an example with extra arguments:

               cargo run --example exname -- --exoption exarg1 exarg2

Exit Status

0: Cargo succeeded.

       •  101: Cargo failed to complete.

Name

       cargo-run — Run the current package

Options

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.
