[−][src]Function std::intrinsics::coverage_counter_subtract
pub unsafe extern "rust-intrinsic" fn coverage_counter_subtract(
index: u32,

🔬 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.
