Function std::intrinsics::uninit

pub unsafe extern "rust-intrinsic" fn uninit<T>() -> T
🔬 This is a nightly-only experimental API. (core_intrinsics #0)intrinsics are unlikely to ever be stabilized, instead they should be used through stabilized interfaces in the rest of the standard library

Creates an uninitialized value.

uninit is unsafe because there is no guarantee of what its contents are. In particular its drop-flag may be set to any state, which means it may claim either dropped or undropped. In the general case one must use ptr::write to initialize memory previous set to the result of uninit.
