Struct ChainHistoryBlockTxAuthCommitmentHash 

pub struct ChainHistoryBlockTxAuthCommitmentHash(/* private fields */);

A block commitment to chain history and transaction auth.

• the chain history tree for all ancestors in the current network upgrade, and
• the transaction authorising data in this block.

Introduced in NU5.

Implementations

impl ChainHistoryBlockTxAuthCommitmentHash

pub fn from_commitments( history_tree_root: &ChainHistoryMmrRootHash, auth_data_root: &AuthDataRoot, ) -> Self

Compute the block commitment from the history tree root and the authorization data root, as specified in ZIP-244.

history_tree_root is the root of the history tree up to and including the previous block. auth_data_root is the root of the Merkle tree of authorizing data commmitments of each transaction in the current block.

Trait Implementations

impl BytesInDisplayOrder<true> for ChainHistoryBlockTxAuthCommitmentHash

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

Returns the bytes in the internal serialized order.

fn from_bytes_in_serialized_order(bytes: [u8; 32]) -> Self

Creates an instance from bytes in the internal serialized order.

fn bytes_in_display_order(&self) -> [u8; BYTE_LEN]

Return the bytes in big-endian byte-order suitable for printing out byte by byte.

fn from_bytes_in_display_order(bytes_in_display_order: &[u8; BYTE_LEN]) -> Self

Convert bytes in big-endian byte-order into big-endian display order.

impl Clone for ChainHistoryBlockTxAuthCommitmentHash

fn clone(&self) -> ChainHistoryBlockTxAuthCommitmentHash

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ChainHistoryBlockTxAuthCommitmentHash

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ChainHistoryBlockTxAuthCommitmentHash

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for ChainHistoryBlockTxAuthCommitmentHash

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

Formats the value using the given formatter.

impl From<[u8; 32]> for ChainHistoryBlockTxAuthCommitmentHash

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

Converts to this type from the input type.

impl From<ChainHistoryBlockTxAuthCommitmentHash> for [u8; 32]

fn from(hash: ChainHistoryBlockTxAuthCommitmentHash) -> Self

Converts to this type from the input type.

impl FromHex for ChainHistoryBlockTxAuthCommitmentHash

type Error = <[u8; 32] as FromHex>::Error

fn from_hex<T: AsRef<[u8]>>(hex: T) -> Result<Self, Self::Error>

Creates an instance of type Self from the given hex string, or fails with a custom error type.

impl PartialEq for ChainHistoryBlockTxAuthCommitmentHash

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl ToHex for &ChainHistoryBlockTxAuthCommitmentHash

fn encode_hex<T: FromIterator<char>>(&self) -> T

Encode the hex strict representing self into the result. Lower case letters are used (e.g. f9b4ca)

fn encode_hex_upper<T: FromIterator<char>>(&self) -> T

Encode the hex strict representing self into the result. Upper case letters are used (e.g. F9B4CA)

impl ToHex for ChainHistoryBlockTxAuthCommitmentHash

fn encode_hex<T: FromIterator<char>>(&self) -> T

Encode the hex strict representing self into the result. Lower case letters are used (e.g. f9b4ca)

fn encode_hex_upper<T: FromIterator<char>>(&self) -> T

Encode the hex strict representing self into the result. Upper case letters are used (e.g. F9B4CA)
