Enum NodeHash 

pub enum NodeHash {
    Hashed(H256),
    Inline(([u8; 31], u8)),
}

Struct representing a trie node hash If the encoded node is less than 32 bits, contains the encoded node itself

Variants

Hashed(H256)

Inline(([u8; 31], u8))

Implementations

impl NodeHash

pub fn from_encoded(encoded: &[u8], crypto: &dyn Crypto) -> NodeHash

Returns the NodeHash of an encoded node (encoded using the NodeEncoder)

pub fn finalize(self, crypto: &dyn Crypto) -> H256

Returns the finalized hash NOTE: This will hash smaller nodes, only use to get the final root hash, not for intermediate node hashes

pub fn is_valid(&self) -> bool

Returns true if the hash is valid The hash will only be considered invalid if it is empty Aka if it has a default value instead of being a product of hash computation

pub fn encode<'a>(&self, encoder: Encoder<'a>) -> Encoder<'a>

Encodes this NodeHash with the given encoder.

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

Trait Implementations

impl Archive for NodeHash

where H256Wrapper: ArchiveWith<H256>, ([u8; 31], u8): Archive,

type Archived = ArchivedNodeHash

The archived representation of this type.

type Resolver = NodeHashResolver

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 AsRef<[u8]> for NodeHash

fn as_ref(&self) -> &[u8]

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for NodeHash

fn clone(&self) -> NodeHash

Converts to this type from the input type.

impl From<NodeHash> for ValueOrHash

fn from(value: NodeHash) -> Self

Converts to this type from the input type.

impl Hash for NodeHash

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,

impl Ord for NodeHash

fn cmp(&self, other: &NodeHash) -> Ordering

This method returns an Ordering between self and other.

impl PartialEq for NodeHash

fn eq(&self, other: &NodeHash) -> 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.
