cargo-llvm-cov-report
Generate coverage report

USAGE:
    cargo llvm-cov report [OPTIONS]

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.

            Skip source code files with file paths that match the given regular expression

        --show-instantiations
            Show instantiations in report

        --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-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

    -q, --quiet
            Display one character per test instead of one line

    -p, --package <SPEC>
            Package to run tests for

    -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

        --target <TRIPLE>
            Build for the target triple

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

        --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.

    -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.

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

        --frozen
            Require Cargo.lock and cache are up to date

        --locked
            Require Cargo.lock is up to date

        --offline
            Run without accessing the network
