This is + intended to help automate tasks that rustc itself already knows how to + tell you to fix! + + Executing cargo fix will under the hood execute cargo-check(1). Any + warnings applicable to your crate will be automatically fixed (if + possible) and all remaining warnings will be displayed when the check + process is finished. For example if you’d like to apply all fixes to + the current package, you can run: + + cargo fix + + which behaves the same as cargo check --all-targets. + + cargo fix is only capable of fixing code that is normally compiled with + cargo check. If code is conditionally enabled with optional features, + you will need to enable those features for that code to be analyzed: + + cargo fix --features foo + + Similarly, other cfg expressions like platform-specific code will need + to pass --target to fix code for the given target. + + cargo fix --target x86_64-pc-windows-gnu + + If you encounter any problems with cargo fix or otherwise have any + questions or feature requests please don’t hesitate to file an issue + at <https://github.com/rust-lang/cargo>. + + Edition migration + The cargo fix subcommand can also be used to migrate a package from one + edition + <https://doc.rust-lang.org/edition-guide/editions/transitioning-an-existing-project-to-a-new-edition.html> + to the next. The general procedure is: + + 1. Run cargo fix --edition. Consider also using the --all-features flag + if your project has multiple features. You may also want to run cargo + fix --edition multiple times with different --target flags if your + project has platform-specific code gated by cfg attributes. + + 2. Modify Cargo.toml to set the edition field + <https://doc.rust-lang.org/cargo/reference/manifest.html#the-edition-field> + to the new edition. + + 3. Run your project tests to verify that everything still works. If new + warnings are issued, you may want to consider running cargo fix again + (without the --edition flag) to apply any suggestions given by the + compiler. + + And hopefully that’s it! Just keep in mind of the caveats mentioned + above that cargo fix cannot update code for inactive features or cfg + expressions. Also, in some rare cases the compiler is unable to + automatically migrate all code to the new edition, and this may require + manual changes after building with the new edition. + +OPTIONS + Fix options + --broken-code + Fix code even if it already has compiler errors. This is useful if + cargo fix fails to apply the changes. It will apply the changes and + leave the broken code in the working directory for you to inspect + and manually fix. + + --edition + Apply changes that will update the code to the next edition. This + will not update the edition in the Cargo.toml manifest, which must + be updated manually after cargo fix --edition has finished. + + --edition-idioms + Apply suggestions that will update code to the preferred style for + the current edition. + + --allow-no-vcs + Fix code even if a VCS was not detected. + + --allow-dirty + Fix code even if the working directory has changes. + + --allow-staged + Fix code even if the working directory has staged changes. + + Package Selection + By default, when no package selection options are given, the packages + selected depend on the selected manifest file (based on the current + working directory if --manifest-path is not given). If the manifest is + the root of a workspace then the workspaces default members are + selected, otherwise only the package defined by the manifest will be + selected. + + The default members of a workspace can be set explicitly with the + workspace.default-members key in the root manifest. If this is not set, + a virtual workspace will include all workspace members (equivalent to + passing --workspace), and a non-virtual workspace will include only the + root crate itself. + + -p spec…, --package spec… + Fix only the specified packages. See cargo-pkgid(1) for the SPEC + format. This flag may be specified multiple times and supports + common Unix glob patterns like *, ? and []. However, to avoid your + shell accidentally expanding glob patterns before Cargo handles + them, you must use single quotes or double quotes around each + pattern. + + --workspace + Fix all members in the workspace. + + --all + Deprecated alias for --workspace. + + --exclude SPEC… + Exclude the specified packages. Must be used in conjunction with the + --workspace flag. This flag may be specified multiple times and + supports common Unix glob patterns like *, ? and []. However, to + avoid your shell accidentally expanding glob patterns before Cargo + handles them, you must use single quotes or double quotes around + each pattern. + + Target Selection + When no target selection options are given, cargo fix will fix all + targets (--all-targets implied). Binaries are skipped if they have + required-features that are missing. + + Passing target selection flags will fix only the specified targets. + + Note that --bin, --example, --test and --bench flags also support common + Unix glob patterns like *, ? and []. 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. + + --lib + Fix the package’s library. + + --bin name… + Fix the specified binary. This flag may be specified multiple times + and supports common Unix glob patterns. + + --bins + Fix all binary targets. + + --example name… + Fix the specified example. This flag may be specified multiple times + and supports common Unix glob patterns. + + --examples + Fix all example targets. + + --test name… + Fix the specified integration test. This flag may be specified + multiple times and supports common Unix glob patterns. + + --tests + Fix all targets in test mode that have the test = true manifest 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 test flag in the manifest settings for the target. + + --bench name… + Fix the specified benchmark. This flag may be specified multiple + times and supports common Unix glob patterns. + + --benches + Fix all targets in benchmark mode that have the bench = true + manifest 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 + bench flag in the manifest settings for the target. + + --all-targets + Fix all targets. This is equivalent to specifying --lib --bins + --tests --benches --examples. + + Feature Selection + 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. + + -F features, --features features + 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. + + Compilation Options + --target triple + Fix for the given architecture. The default is the host + architecture. The general format of the triple is + <arch><sub>-<vendor>-<sys>-<abi>. Run rustc --print target-list for + a list of supported targets. This flag may be specified multiple + times. + + 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. + + -r, --release + Fix optimized artifacts with the release profile. See also the + --profile option for choosing a specific profile by name. + + --profile name + Fix with the given profile. + + As a special case, specifying the test profile will also enable + checking in test mode which will enable checking tests and enable + the test cfg option. See rustc tests + <https://doc.rust-lang.org/rustc/tests/index.html> for more detail. + + See the the reference + <https://doc.rust-lang.org/cargo/reference/profiles.html> for more + details on profiles. + + --ignore-rust-version + Fix the target even if the selected Rust compiler is older than the + required Rust version as configured in the project’s rust-version + field. + + --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: + + o 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. + + o json (unstable, requires -Zunstable-options): Emit + machine-readable JSON information about timing information. + + Output Options + --target-dir directory + Directory for all generated artifacts and intermediate files. May + also be specified with the CARGO_TARGET_DIR environment variable, or + the build.target-dir config value + <https://doc.rust-lang.org/cargo/reference/config.html>. Defaults to + target in the root of the workspace. + + Display Options + -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.verbose + config value + <https://doc.rust-lang.org/cargo/reference/config.html>. + + -q, --quiet + Do not print cargo log messages. May also be specified with the + term.quiet config value + <https://doc.rust-lang.org/cargo/reference/config.html>. + + --color when + Control when colored output is used. Valid values: + + o auto (default): Automatically detect if color support is + available on the terminal. + + o always: Always display colors. + + o never: Never display colors. + + May also be specified with the term.color config value + <https://doc.rust-lang.org/cargo/reference/config.html>. + + --message-format fmt + The output format for diagnostic messages. Can be specified multiple + times and consists of comma-separated values. Valid values: + + o human (default): Display in a human-readable text format. + Conflicts with short and json. + + o short: Emit shorter, human-readable text messages. Conflicts with + human and json. + + o json: Emit JSON messages to stdout. See the reference + <https://doc.rust-lang.org/cargo/reference/external-tools.html#json-messages> + for more details. Conflicts with human and short. + + o json-diagnostic-short: Ensure the rendered field of JSON messages + contains the “short” rendering from rustc. Cannot be used + with human or short. + + o 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. + + o 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. + + Manifest Options + --manifest-path path + Path to the Cargo.toml file. By default, Cargo searches for the + Cargo.toml file in the current directory or any parent directory. + + --frozen, --locked + Either of these flags requires that the Cargo.lock file is + up-to-date. If the lock file is missing, or it needs to be updated, + Cargo will exit with an error. The --frozen flag 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.lock file is up-to-date (such as a CI build) or want to avoid + network access. + + --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.offline config value + <https://doc.rust-lang.org/cargo/reference/config.html>. + + Common Options + +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 rustup documentation + <https://rust-lang.github.io/rustup/overrides.html> for more + information about how toolchain overrides work. + + --config KEY=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-line overrides section + <https://doc.rust-lang.org/cargo/reference/config.html#command-line-overrides> + for more information. + + -C PATH + 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 -C + path/to/my-project build. + + This option is only available on the nightly channel + <https://doc.rust-lang.org/book/appendix-07-nightly-rust.html> and + requires the -Z unstable-options flag to enable (see #10098 + <https://github.com/rust-lang/cargo/issues/10098>). + + -h, --help + Prints help information. + + -Z flag + Unstable (nightly-only) flags to Cargo. Run cargo -Z help for + details. + + Miscellaneous Options + -j N, --jobs N + Number of parallel jobs to run. May also be specified with the + build.jobs config value + <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. + 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. + Unstable, requires -Zunstable-options. + +ENVIRONMENT + See the reference + <https://doc.rust-lang.org/cargo/reference/environment-variables.html> + for details on environment variables that Cargo reads. + +EXIT STATUS + o 0: Cargo succeeded. + + o 101: Cargo failed to complete. + +EXAMPLES + 1.
