Function std::intrinsics::uninit [] [src]

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

: 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`uninitis 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 useptr::writeto initialize memory previous set to the result ofuninit`.
