Implementations§
source§impl<T> ArchivedOption<T>
impl<T> ArchivedOption<T>
sourcepub fn ok_or<E>(self, err: E) -> Result<T, E>
pub fn ok_or<E>(self, err: E) -> Result<T, E>
Transforms the ArchivedOption<T>
into a Result<T, E>
, mapping
Some(v)
to Ok(v)
and None
to Err(err)
.
sourcepub fn unwrap_or(self, default: T) -> T
pub fn unwrap_or(self, default: T) -> T
Returns the contained Some
value or a provided default.
sourcepub fn unwrap_or_else<F: FnOnce() -> T>(self, f: F) -> T
pub fn unwrap_or_else<F: FnOnce() -> T>(self, f: F) -> T
Returns the contained Some
value or computes it from a closure.
sourcepub fn as_seal(this: Seal<'_, Self>) -> Option<Seal<'_, T>>
pub fn as_seal(this: Seal<'_, Self>) -> Option<Seal<'_, T>>
Converts from Seal<'_, ArchivedOption<T>>
to Option<Seal<'_, T>>
.
sourcepub fn iter_mut(&mut self) -> Iter<&mut T> ⓘ
pub fn iter_mut(&mut self) -> Iter<&mut T> ⓘ
Returns an iterator over the mutable possibly-contained value.
sourcepub fn iter_seal(this: Seal<'_, Self>) -> Iter<Seal<'_, T>> ⓘ
pub fn iter_seal(this: Seal<'_, Self>) -> Iter<Seal<'_, T>> ⓘ
Returns an iterator over the sealed 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.
