🔬 This is a nightly-only experimental API. (core_intrinsics)

intrinsics are unlikely to ever be stabilized, instead they should be used through stabilized interfaces in the rest of the standard library

This marker identifies a code region and two other counters or counter expressions whose difference is the number of times the code region was executed. (See coverage_counter_add for more information.)
