[][src]Function core::intrinsics::coverage_unreachable

pub unsafe extern "rust-intrinsic" fn coverage_unreachable(
    start_byte_pos: u32,
    end_byte_pos: 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 to be added to the "coverage map" to indicate source code that can never be reached. (See coverage_counter_add for more information.)
