Struct zebra_chain::transaction::auth_digest::AuthDigest

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

An authorizing data commitment hash as specified in ZIP-244.

Note: Zebra displays transaction and block hashes in big-endian byte-order, following the u256 convention set by Bitcoin and zcashd.

Trait Implementations

impl Arbitrary for AuthDigest

type Parameters = <[u8; 32] as Arbitrary>::Parameters

The type of parameters that arbitrary_with accepts for configuration of the generated Strategy. Parameters must implement Default.

type Strategy = Map<<[u8; 32] as Arbitrary>::Strategy, fn(_: [u8; 32]) -> AuthDigest>

The type of Strategy used to generate values of type Self.

fn arbitrary_with(_top: Self::Parameters) -> Self::Strategy

Generates a Strategy for producing arbitrary values of type the implementing type (Self). The strategy is passed the arguments given in args.

fn arbitrary() -> Self::Strategy

Generates a Strategy for producing arbitrary values of type the implementing type (Self).

Computes the authorizing data commitment for a transaction.

Panics

If passed a pre-v5 transaction.

impl From<AuthDigest> for [u8; 32]

fn from(auth_digest: AuthDigest) -> Self

Converts to this type from the input type.

impl From<Transaction> for AuthDigest

fn from(transaction: Transaction) -> Self

Computes the authorizing data commitment for a transaction.

Panics

If passed a pre-v5 transaction.

impl FromHex for AuthDigest

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 FromIterator<AuthDigest> for AuthDataRoot

fn from_iter<I>(hashes: I) -> Self

where I: IntoIterator<Item = AuthDigest>,

Creates a value from an iterator.

impl FromStr for AuthDigest

type Err = SerializationError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Hash for AuthDigest

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 AuthDigest

fn eq(&self, other: &AuthDigest) -> 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 ToHex for &AuthDigest

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