Deserialize the fields using serde.

const REVISIONS: NonZero<usize> = _

fn heap_size(_value: &Self::Fields<'_>) -> Option<usize>

Returns the size of any heap allocations in the output value, in bytes.

impl<'db> Debug for VariancesOf<'db>

fn fmt(&self, fmt: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'db> Default for VariancesOf<'db>

fn default() -> Self

Returns the “default value” for a type.

impl<'db> FromId for VariancesOf<'db>

fn from_id(id: Id) -> Self

impl<'db> HasJar for VariancesOf<'db>

const KIND: JarKind = zalsa_::JarKind::Struct

The [JarKind] for Self::Jar.

type Jar = JarImpl<VariancesOf<'static>>

The [Jar] associated with this ingredient.

impl<'db> Hash for VariancesOf<'db>

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<'db> IntoIterator for VariancesOf<'db>

type Item = Variance

The type of the elements being iterated over.

type IntoIter = <VariancesOf<'db> as SliceLike>::IntoIter

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl<'db> PartialEq for VariancesOf<'db>

fn eq(&self, other: &VariancesOf<'db>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
