Implementations

impl ArchivedOptionNonZeroU32

pub fn is_none(&self) -> bool

Returns true if the option is a None value.

pub fn is_some(&self) -> bool

Returns true if the option is a Some value.

pub fn as_ref(&self) -> Option<&Archived<NonZeroU32>>

Converts to an Option<&Archived<NonZeroU32>>

pub fn as_mut(&mut self) -> Option<&mut Archived<NonZeroU32>>

Converts to an Option<&mut Archived<NonZeroU32>>

pub fn as_seal(this: Seal<'_, Self>) -> Option<Seal<'_, Archived<NonZeroU32>>>

Converts from Seal<'_, ArchivedOptionNonZeroU32> to Option<Seal<'_, Archived<NonZeroU32>>>.

pub fn take(&mut self) -> Option<Archived<NonZeroU32>>

Takes the value out of the option, leaving a None in its place.

pub fn iter(&self) -> Iter<&Archived<NonZeroU32>>

Returns an iterator over the possibly-contained value.

pub fn iter_mut(&mut self) -> Iter<&mut Archived<NonZeroU32>>

Returns an iterator over the mutable possibly-contained value.

pub fn iter_seal(this: Seal<'_, Self>) -> Iter<Seal<'_, Archived<NonZeroU32>>>

Returns an iterator over the sealed mutable possibly-contained value.

pub fn get_or_insert(&mut self, v: NonZeroU32) -> &mut Archived<NonZeroU32>

Inserts v into the option if it is None, then returns a mutable reference to the contained value.

pub fn get_or_insert_with<F>(&mut self, f: F) -> &mut Archived<NonZeroU32>

where F: FnOnce() -> NonZeroU32,

Inserts a value computed from f into the option if it is None, then returns a mutable reference to the contained value.

pub fn resolve_from_option(field: Option<NonZeroU32>, out: Place<Self>)

Resolves an ArchivedOptionNonZero from an Option<NonZero>.
