Function mapping_version

Source 
pub(crate) fn mapping_version() -> u32
Expand description

Returns LLVM’s coverage::CovMapVersion::CurrentVersion (CoverageMapping.h) as a raw numeric value. For historical reasons, the numeric value is 1 less than the number in the version’s name, so Version7 is actually 6u32.
