impl<T> ArchivedOption<T>
sourcepub fn as_pin_ref(self: Pin<&Self>) -> Option<Pin<&T>>
pub fn as_pin_ref(self: Pin<&Self>) -> Option<Pin<&T>>
Converts from Pin<&ArchivedOption<T>>
to Option<Pin<&T>>
.
sourcepub fn as_pin_mut(self: Pin<&mut Self>) -> Option<Pin<&mut T>>
pub fn as_pin_mut(self: Pin<&mut Self>) -> Option<Pin<&mut T>>
Converts from Pin<&mut ArchivedOption<T>>
to Option<Pin<&mut T>>
.
sourcepub const fn iter(&self) -> Iter<'_, T> ⓘ
pub const fn iter(&self) -> Iter<'_, T> ⓘ
Returns an iterator over the possibly contained value.
sourcepub fn iter_mut(&mut self) -> IterMut<'_, T> ⓘ
pub fn iter_mut(&mut self) -> IterMut<'_, T> ⓘ
Returns a mutable iterator over the possibly contained value.
sourcepub fn get_or_insert(&mut self, v: T) -> &mut T
pub fn get_or_insert(&mut self, v: T) -> &mut T
Inserts v
into the option if it is None
, then returns a mutable
reference to the contained value.
sourcepub fn get_or_insert_with<F: FnOnce() -> T>(&mut self, f: F) -> &mut T
pub fn get_or_insert_with<F: FnOnce() -> T>(&mut self, f: F) -> &mut T
Inserts a value computed from f
into the option if it is None
, then
returns a mutable reference to the contained value.
source§impl<T: Deref> ArchivedOption<T>
impl<T: Deref> ArchivedOption<T>
source§impl<T: DerefMut> ArchivedOption<T>
impl<T: DerefMut> ArchivedOption<T>
sourcepub fn as_deref_mut(&mut self) -> Option<&mut <T as Deref>::Target>
pub fn as_deref_mut(&mut self) -> Option<&mut <T as Deref>::Target>
Converts from &mut ArchivedOption<T>
to Option<&mut T::Target>
.
Leaves the original ArchivedOption
in-place, creating a new Option
with a mutable
reference to the inner type’s Deref::Target
type.
