Expand description

Corresponds to enum llvm::coverage::CounterMappingRegion::RegionKind.

Must match the layout of LLVMRustCounterMappingRegionKind.

Variants§

§

CodeRegion = 0

A CodeRegion associates some code with a counter

§

ExpansionRegion = 1

An ExpansionRegion represents a file expansion region that associates a source range with the expansion of a virtual source file, such as for a macro instantiation or #include file.

§

SkippedRegion = 2

A SkippedRegion represents a source range with code that was skipped by a preprocessor or similar means.

§

GapRegion = 3

A GapRegion is like a CodeRegion, but its count is only set as the line execution count when its the only region in the line.

§

BranchRegion = 4

A BranchRegion represents leaf-level boolean expressions and is associated with two counters, each representing the number of times the expression evaluates to true or false.

§

MCDCDecisionRegion = 5

A DecisionRegion represents a top-level boolean expression and is associated with a variable length bitmap index and condition number.

§

MCDCBranchRegion = 6

A Branch Region can be extended to include IDs to facilitate MC/DC.
