pub struct CounterMappingRegion { counter: Counter, false_counter: Counter, mcdc_params: Parameters, file_id: u32, expanded_file_id: u32, start_line: u32, start_col: u32, end_line: u32, end_col: u32, kind: RegionKind, }
Expand description

This struct provides LLVM’s representation of a “CoverageMappingRegion”, encoded into the coverage map, in accordance with the LLVM Code Coverage Mapping Format. The struct composes fields representing the Counter type and value(s) (injected counter ID, or expression type and operands), the source file (an indirect index into a “filenames array”, encoded separately), and source location (start and end positions of the represented code region).

Corresponds to struct llvm::coverage::CounterMappingRegion.

Must match the layout of LLVMRustCounterMappingRegion.

Fields§

§counter: Counter

The counter type and type-dependent counter data, if any.

§false_counter: Counter

If the RegionKind is a BranchRegion, this represents the counter for the false branch of the region.

§mcdc_params: Parameters§file_id: u32

An indirect reference to the source filename. In the LLVM Coverage Mapping Format, the file_id is an index into a function-specific virtual_file_mapping array of indexes that, in turn, are used to look up the filename for this region.

§expanded_file_id: u32

If the RegionKind is an ExpansionRegion, the expanded_file_id can be used to find the mapping regions created as a result of macro expansion, by checking if their file id matches the expanded file id.

§start_line: u32

1-based starting line of the mapping region.

§start_col: u32

1-based starting column of the mapping region.

§end_line: u32

1-based ending line of the mapping region.

§end_col: u32

1-based ending column of the mapping region. If the high bit is set, the current mapping region is a gap area.

§kind: RegionKind
