Function std::intrinsics::panic_if_zero_invalid

pub unsafe extern "rust-intrinsic" fn panic_if_zero_invalid<T>()

🔬 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

A guard for unsafe functions that cannot ever be executed if T does not permit zero-initialization: This will statically either panic, or do nothing.
