cargo-llvm-cov-run
Run a binary or example and generate coverage report

USAGE:
    cargo llvm-cov run [OPTIONS] [-- <args>...]

ARGS:
    <args>...
            Arguments for the binary

OPTIONS:
        --json
            Export coverage data in "json" format

            If --output-path is not specified, the report will be printed to stdout.

            This internally calls `llvm-cov export -format=text`. See
            <https://llvm.org/docs/CommandGuide/llvm-cov.html#llvm-cov-export> for more.

        --lcov
            Export coverage data in "lcov" format

            If --output-path is not specified, the report will be printed to stdout.

            This internally calls `llvm-cov export -format=lcov`. See
            <https://llvm.org/docs/CommandGuide/llvm-cov.html#llvm-cov-export> for more.

        --cobertura
            Export coverage data in "cobertura" XML format

            If --output-path is not specified, the report will be printed to stdout.

            This internally calls `llvm-cov export -format=lcov` and then converts to cobertura.xml.
            See <https://llvm.org/docs/CommandGuide/llvm-cov.html#llvm-cov-export> for more.

        --codecov
            Export coverage data in "Codecov Custom Coverage" format

            If --output-path is not specified, the report will be printed to stdout.

            This internally calls `llvm-cov export -format=json` and then converts to codecov.json.
            See <https://llvm.org/docs/CommandGuide/llvm-cov.html#llvm-cov-export> for more.

        --text
            Generate coverage report in "text" format

            If --output-path or --output-dir is not specified, the report will be printed to stdout.

            This internally calls `llvm-cov show -format=text`. See
            <https://llvm.org/docs/CommandGuide/llvm-cov.html#llvm-cov-show> for more.

        --html
            Generate coverage report in "html" format

            If --output-dir is not specified, the report will be generated in `target/llvm-cov/html`
            directory.

            This internally calls `llvm-cov show -format=html`. See
            <https://llvm.org/docs/CommandGuide/llvm-cov.html#llvm-cov-show> for more.

        --open
            Generate coverage reports in "html" format and open them in a browser after the
            operation.

            See --html for more.

        --summary-only
            Export only summary information for each file in the coverage data

            This flag can only be used together with --json, --lcov, or --cobertura.

        --output-path <PATH>
            Specify a file to write coverage data into.

            This flag can only be used together with --json, --lcov, --cobertura, or --text.
            See --output-dir for --html and --open.

        --output-dir <DIRECTORY>
            Specify a directory to write coverage report into (default to `target/llvm-cov`).

            This flag can only be used together with --text, --html, or --open. See also
            --output-path.

        --failure-mode <any|all>
            Fail if `any` or `all` profiles cannot be merged (default to `any`)

        --ignore-filename-regex <PATTERN>
            Skip source code files with file paths that match the given regular expression

        --show-instantiations
            Show instantiations in report

        --no-cfg-coverage
            Unset cfg(coverage), which is enabled when code is built using cargo-llvm-cov

        --no-cfg-coverage-nightly
            Unset cfg(coverage_nightly), which is enabled when code is built using cargo-llvm-cov
            and nightly compiler

        --no-report
            Run tests, but don't generate coverage report

        --no-clean
            Build without cleaning any old build artifacts

        --no-rustc-wrapper
            Build without setting RUSTC_WRAPPER

            By default, cargo-llvm-cov sets RUSTC_WRAPPER. This is usually optimal
            for compilation time, execution time, and disk usage.

            When both this flag and --target option are used, coverage for proc-macro and
            build script will not be displayed because cargo does not pass RUSTFLAGS to them.

        --fail-under-functions <MIN>
            Exit with a status of 1 if the total function coverage is less than MIN percent

        --fail-under-lines <MIN>
            Exit with a status of 1 if the total line coverage is less than MIN percent

        --fail-under-file-lines <MIN>
            Exit with a status of 1 if the files line coverage is less than MIN percent

        --fail-under-regions <MIN>
            Exit with a status of 1 if the total region coverage is less than MIN percent

        --fail-uncovered-lines <MAX>
            Exit with a status of 1 if the uncovered lines are greater than MAX

        --fail-uncovered-regions <MAX>
            Exit with a status of 1 if the uncovered regions are greater than MAX

        --fail-uncovered-functions <MAX>
            Exit with a status of 1 if the uncovered functions are greater than MAX

        --show-missing-lines
            Show lines with no coverage

        --include-build-script
            Include build script in coverage report

        --dep-coverage <NAME>
            Show coverage of the specified dependencies (space or comma separated list)
            instead of the crates in the current workspace.

        --skip-functions
            Skip exporting per-function coverage data.

            This flag can only be used together with --json, --lcov, or --cobertura.

        --branch
            Enable branch coverage. (unstable)

            This flag is unstable. See <https://github.com/taiki-e/cargo-llvm-cov/issues/8> for
            more.

        --mcdc
            Enable mcdc coverage. (unstable)

        --ignore-run-fail
            Run all tests regardless of failure and generate report

            If tests failed but report generation succeeded, exit with a status of 0.

    -q, --quiet
            No output printed to stdout

        --bin <NAME>
            Name of the bin target to run

        --example <NAME>
            Name of the example target to run

        --exclude-from-report <SPEC>
            Exclude packages from the report

    -p, --package <SPEC>
            Package with the target to run

    -j, --jobs <N>
            Number of parallel jobs, defaults to # of CPUs

    -r, --release
            Build artifacts in release mode, with optimizations

        --profile <PROFILE-NAME>
            Build artifacts with the specified profile

    -F, --features <FEATURES>
            Space or comma separated list of features to activate

        --all-features
            Activate all available features

        --no-default-features
            Do not activate the `default` feature

        --target <TRIPLE>
            Build for the target triple

        --coverage-target-only
            Activate coverage reporting only for the target triple

            Activate coverage reporting only for the target triple specified via `--target`. This is
            important, if the project uses multiple targets via the cargo bindeps feature, and not
            all targets can use `instrument-coverage`, e.g. a microkernel, or an embedded binary.

            When this flag is used, coverage for proc-macro and build script will not be displayed.

        --coverage-host-only
            Activate coverage reporting only for the host target triple

            In cross-compilation builds, this can be used to get coverage for build scripts and
            proc-macro while skipping coverage for the cross-compiled target which may not support
            `instrument-coverage`.

    -v, --verbose
            Use verbose output

            Use -vv (-vvv) to propagate verbosity to cargo.

        --color <WHEN>
            Coloring: auto, always, never

        --remap-path-prefix
            Use --remap-path-prefix for workspace root

            Note that this does not fully compatible with doctest.

        --include-ffi
            Include coverage of C/C++ code linked to Rust library/binary

            Note that `CC`/`CXX`/`LLVM_COV`/`LLVM_PROFDATA` environment variables must be set to
            Clang/LLVM compatible with the LLVM version used in rustc.

        --keep-going
            Do not abort the build as soon as there is an error (unstable)

        --ignore-rust-version
            Ignore `rust-version` specification in packages

        --manifest-path <PATH>
            Path to Cargo.toml

        --locked
            Require Cargo.lock is up to date

        --offline
            Run without accessing the network

    -Z <FLAG>

            details
