Struct CoverageMapping

pub struct CoverageMapping<'a> {
    pub mapping_info: Vec<CoverageMappingInfo>,
    /* private fields */
}

Stores the instrumentation profile and information from the coverage mapping sections in the object files in order to construct a coverage report. Inspired, from the LLVM implementation with some differences/simplifications due to the fact this only hands instrumentation profiles for coverage.

So what the LLVM one has that this one doesn’t yet:

1. DenseMap<size_t, DenseSet<size_t>> RecordProvenance
2. std::vector functions (this is probably taken straight from InstrumentationProfile
3. DenseMap<size_t, SmallVector<unsigned, 0>> FilenameHash2RecordIndices
4. Vec<Pair<String, u64>> FuncHashMismatches

Fields

mapping_info: Vec<CoverageMappingInfo>

Implementations

impl<'a> CoverageMapping<'a>

where P: FnMut(&[PathBuf]) -> bool,

pub fn generate_report(&self) -> CoverageReport
