Struct Hash 

pub struct Hash(pub [u8; 32]);

32-byte hash (SHA-256)

Tuple Fields

0: [u8; 32]

Implementations

impl Hash

pub const fn new(bytes: [u8; 32]) -> Hash

Create hash from bytes

pub fn hash(data: &[u8]) -> Hash

Hash arbitrary data

pub fn hash_two_parts(part_a: &[u8], part_b: &[u8]) -> Hash

PERF-OPT 7: Hash two byte slices without concatenating them first. Avoids a heap allocation (Vec::with_capacity + extend_from_slice) on every call in hot paths like Merkle leaf computation where we hash(pubkey || account_bytes). With 100+ dirty accounts per block, this eliminates 100+ allocations per state root computation.

pub fn to_hex(&self) -> String

Convert to hex string

pub fn from_hex(s: &str) -> Result<Hash, String>

Parse from hex string

Trait Implementations

impl Clone for Hash

fn clone(&self) -> Hash

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Hash

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

Formats the value using the given formatter.

impl Default for Hash

fn default() -> Hash

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Hash

fn deserialize<__D>( __deserializer: __D, ) -> Result<Hash, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Hash

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

Formats the value using the given formatter.

impl Hash for Hash

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

where __H: Hasher,

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 Hash

fn eq(&self, other: &Hash) -> 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 Serialize for Hash

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for Hash

impl Eq for Hash

impl StructuralPartialEq for Hash
