| CARGO-REPORT-FUTURE-INCOMPATIBILITIES(1) |
| |
| NAME |
| cargo-report-future-incompatibilities — Reports any crates which will |
| eventually stop compiling |
| |
| SYNOPSIS |
| cargo report future-incompatibilities [options] |
| |
| DESCRIPTION |
| Displays a report of future-incompatible warnings that were emitted |
| during previous builds. These are warnings for changes that may become |
| hard errors in the future, causing dependencies to stop building in a |
| future version of rustc. |
| |
| For more, see the chapter on Future incompat report |
| <https://doc.rust-lang.org/cargo/reference/future-incompat-report.html>. |
| |
| OPTIONS |
| --id id |
| Show the report with the specified Cargo-generated id. If not |
| specified, shows the most recent report. |
| |
| Package Selection |
| 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 |
| The package to display a report for. See cargo-pkgid(1) for the SPEC |
| format. |
| |
| 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>. |
| |
| Manifest Options |
| --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: |
| |
| o The lock file is missing. |
| |
| o 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.offline config value |
| <https://doc.rust-lang.org/cargo/reference/config.html>. |
| |
| --frozen |
| Equivalent to specifying both --locked and --offline. |
| |
| 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. |
| |
| 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. |
| |
