pub struct Uninit;
Expand description
A type implementing InitStatus
indicating that the value is completely unitialized.
Trait Implementations
sourceimpl<T> InitStatus<T> for Uninit
impl<T> InitStatus<T> for Uninit
type Value = MaybeUninit<T>
type Value = MaybeUninit<T>
The type of the values with the initialization status described by Self
.
sourcefn init(out: &mut MaybeUninit<T>, t: T)
fn init(out: &mut MaybeUninit<T>, t: T)
Initialize the given element.
sourceunsafe fn assume_init_ref(t: &MaybeUninit<T>) -> &T
unsafe fn assume_init_ref(t: &MaybeUninit<T>) -> &T
Retrieve a reference to the element, assuming that it is initialized. Read more
sourceunsafe fn assume_init_mut(t: &mut MaybeUninit<T>) -> &mut T
unsafe fn assume_init_mut(t: &mut MaybeUninit<T>) -> &mut T

sourcefn to_subset(&self) -> Option<SS>
fn to_subset(&self) -> Option<SS>
The inverse inclusion map: attempts to construct self
from the equivalent element of its
superset. Read more
sourcefn is_in_subset(&self) -> bool
fn is_in_subset(&self) -> bool
Checks if self
is actually part of its subset T
(and can be converted to it).
sourcefn to_subset_unchecked(&self) -> SS
fn to_subset_unchecked(&self) -> SS
Use with care! Same as self.to_subset
but without any property checks. Always succeeds.
sourcefn from_subset(element: &SS) -> SP
fn from_subset(element: &SS) -> SP
The inclusion map: converts self
to the equivalent element of its superset.
