Struct BlockHash 

#[repr(transparent)]
pub struct BlockHash(pub [u8; 32]);

Block hash: newtype wrapper for type safety

Prevents mixing up block hashes with other Hash values (e.g., transaction hashes, merkle roots). Uses #[repr(transparent)] for zero-cost abstraction - same memory layout as Hash.

Tuple Fields

0: [u8; 32]

Implementations

impl BlockHash

pub fn new(hash: [u8; 32]) -> BlockHash

Create a new BlockHash from a Hash

pub fn as_hash(self) -> [u8; 32]

Get the inner Hash value

pub fn as_hash_ref(&self) -> &[u8; 32]

Get a reference to the inner Hash

Trait Implementations

impl Clone for BlockHash

fn clone(&self) -> BlockHash

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BlockHash

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

Formats the value using the given formatter.

impl Deref for BlockHash

type Target = [u8; 32]

The resulting type after dereferencing.

fn deref(&self) -> &<BlockHash as Deref>::Target

Dereferences the value.

impl<'de> Deserialize<'de> for BlockHash

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<[u8; 32]> for BlockHash

fn from(hash: [u8; 32]) -> BlockHash

Converts to this type from the input type.

impl From<BlockHash> for [u8; 32]

fn from(hash: BlockHash) -> [u8; 32]

Converts to this type from the input type.

impl Hash for BlockHash

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 BlockHash

fn eq(&self, other: &BlockHash) -> 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 BlockHash

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 BlockHash

impl Eq for BlockHash
