Enum InstrumentCoverage

Source
pub enum InstrumentCoverage {
    No,
    Yes,
}
Expand description

The different settings that the -C instrument-coverage flag can have.

Coverage instrumentation now supports combining -C instrument-coverage with compiler and linker optimization (enabled with -O or -C opt-level=1 and higher). Nevertheless, there are many variables, depending on options selected, code structure, and enabled attributes. If errors are encountered, either while compiling or when generating llvm-cov show reports, consider lowering the optimization level, or including/excluding -C link-dead-code.

Variants§

§

No

-C instrument-coverage=no (or off, false etc.)

§

Yes

-C instrument-coverage or -C instrument-coverage=yes
