Function no_std_compat::intrinsics::unreachable

pub const unsafe extern "rust-intrinsic" fn unreachable() -> !

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

Informs the optimizer that this point in the code is not reachable, enabling further optimizations.

N.B., this is very different from the unreachable!() macro: Unlike the macro, which panics when it is executed, it is undefined behavior to reach code marked with this function.

The stabilized version of this intrinsic is core::hint::unreachable_unchecked.
