|CARGO-RUN(1)||General Commands Manual||CARGO-RUN(1)|
cargo-run - Run the current package
cargo run [options] [-- args]
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.
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.
-p spec, --package spec
When no target selection options are given, cargo run 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.
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 the features documentation <https://doc.rust-lang.org/cargo/reference/features.html#command-line-feature-options> for more details.
This may also be specified with the build.target config value <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 build cache <https://doc.rust-lang.org/cargo/guide/build-cache.html> documentation for more details.
May also be specified with the term.color config value <https://doc.rust-lang.org/cargo/reference/config.html>.
These may be used in environments where you want to assert that the Cargo.lock file is up-to-date (such as a CI build) or want to avoid network access.
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.offline config value <https://doc.rust-lang.org/cargo/reference/config.html>.
-j N, --jobs N
Profiles may be used to configure compiler options such as optimization levels and debug settings. See the reference <https://doc.rust-lang.org/cargo/reference/profiles.html> for more details.
Profile selection depends on the target and crate being built. By default the dev or test profiles are used. If the --release flag is given, then the release or bench profiles are used.
|Target||Default Profile||--release Profile|
|lib, bin, example||dev||release|
|test, bench, or any target in "test" or "bench" mode||test||bench|
Dependencies use the dev/release profiles.
See the reference <https://doc.rust-lang.org/cargo/reference/environment-variables.html> for details on environment variables that Cargo reads.
