Struct ResolvedMappings

struct ResolvedMappings {
    source_file: Arc<SourceFile>,
    code_mappings: Vec<CodeMapping>,
    branch_mappings: Vec<BranchMapping>,
}

Expand description

Intermediate representation of coverage mappings, after all mapping spans have been resolved to file coordinates (or discarded), but before producing a final llvm_cov::Regions.

Having a separate resolution step makes it easier to handle edge cases where a function (or someday an expansion) manages to lose all of its spans, without accidentally emitting invalid covfun records containing empty files.

Fields§

§source_file: Arc<SourceFile>

Source file for all of the spans::Coords in these mappings.
