Enum HistoricalLogDiff 

pub enum HistoricalLogDiff {
    Unchanged,
    Append(Vec<u8>),
}

Delta representation for the historical summaries list.

Because historical summaries/roots are appended strictly once every 8,192 slots, the number of new summaries/roots between two slots is mathematically deterministic. This diff enforces that invariant rather than comparing byte lengths.

Variants

Unchanged

The 8,192-slot boundary was not crossed.

Append(Vec<u8>)

Contains the raw SSZ bytes of the new items (64 bytes each).

Trait Implementations

impl Archive for HistoricalLogDiff

where Vec<u8>: Archive,

type Archived = ArchivedHistoricalLogDiff

The archived representation of this type.

type Resolver = HistoricalLogDiffResolver

The resolver for this type. It must contain all the additional information from serializing needed to make the archived type from the normal type.

fn resolve( &self, resolver: <Self as Archive>::Resolver, out: Place<<Self as Archive>::Archived>, )

Creates the archived version of this value at the given position and writes it to the given output.

const COPY_OPTIMIZATION: CopyOptimization<Self> = _

An optimization flag that allows the bytes of this type to be copied directly to a writer instead of calling serialize.

impl Clone for HistoricalLogDiff

fn clone(&self) -> HistoricalLogDiff

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for HistoricalLogDiff

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

Formats the value using the given formatter.

impl<__D: Fallible + ?Sized> Deserialize<HistoricalLogDiff, __D> for Archived<HistoricalLogDiff>

where Vec<u8>: Archive, <Vec<u8> as Archive>::Archived: Deserialize<Vec<u8>, __D>,

fn deserialize( &self, deserializer: &mut __D, ) -> Result<HistoricalLogDiff, <__D as Fallible>::Error>

Deserializes using the given deserializer

impl Eq for HistoricalLogDiff

impl PartialEq for HistoricalLogDiff

fn eq(&self, other: &HistoricalLogDiff) -> bool

Equality operator ==.

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

Inequality operator !=.

impl<__S: Fallible + ?Sized> Serialize<__S> for HistoricalLogDiff

where Vec<u8>: Serialize<__S>,

fn serialize( &self, serializer: &mut __S, ) -> Result<<Self as Archive>::Resolver, <__S as Fallible>::Error>

Writes the dependencies for the object and returns a resolver that can create the archived type.
