Sourcepub unsafe fn new_unchecked(inner: T) -> Self
pub unsafe fn new_unchecked(inner: T) -> Self
Sourcepub unsafe fn get_unchecked(&self) -> &T
pub unsafe fn get_unchecked(&self) -> &T
Get the inner value, without consuming the Unused wrapper.
§Safety
The user need to make sure that the value stays unused.
