Module coverage

Metadata from source code coverage analysis and instrumentation.

Structs

• BlockMarkerId
  Used by CoverageKind::BlockMarker to mark blocks during THIR-to-MIR lowering, so that those blocks can be identified later.
• BranchSpan
• ConditionId
  ID of a mcdc condition. Used by llvm to check mcdc coverage.
• ConditionInfo
• CounterId
  ID of a coverage counter. Values ascend from 0.
• CoverageInfoHi
  Coverage information for a function, recorded during MIR building and attached to the corresponding mir::Body. Used by the InstrumentCoverage MIR pass.
• DecisionInfo
• Expression
• ExpressionId
  ID of a coverage-counter expression. Values ascend from 0.
• FunctionCoverageInfo
  Stores per-function coverage information attached to a mir::Body, to be used in conjunction with the individual coverage statements injected into the function’s basic blocks.
• MCDCBranchSpan
• MCDCDecisionSpan
• Mapping
• SourceRegion

Enums

• CovTerm
  Enum that can hold a constant zero value, the ID of an physical coverage counter, or the ID of a coverage-counter expression.
• CoverageKind
• MappingKind
