[−][src]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
.
