Enum NodeHashAlgorithm 

pub enum NodeHashAlgorithm {
    MerkleDB,
    Ethereum,
}

The hash algorithm used by the node store.

This must currently match the compile-time option. However, it will eventually be made a runtime option when initializing the node store. Therefore, the option is required when initializing and opening the node store to ensure compatibility and to detect any mismatches.

Variants

MerkleDB

Use the MerkleDB node hashing algorithm, with sha256 as the hash function.

Ethereum

Use the Ethereum state trie node hashing algorithm, with keccak256 as the hash function.

Implementations

impl NodeHashAlgorithm

pub const fn matches_compile_option(self) -> bool

Returns whether this hash algorithm matches the compile-time option.

Trait Implementations

impl Clone for NodeHashAlgorithm

fn clone(&self) -> NodeHashAlgorithm

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NodeHashAlgorithm

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

Formats the value using the given formatter.

impl Hash for NodeHashAlgorithm

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 PartialEq for NodeHashAlgorithm

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

impl TryFrom<u64> for NodeHashAlgorithm

type Error = NodeHashAlgorithmTryFromIntError

The type returned in the event of a conversion error.

fn try_from(value: u64) -> Result<Self, Self::Error>

Performs the conversion.
