pub const fn as_bytes(&self) -> &[u8]

Returns a slice of bytes representing the digest.

pub fn from_base58<T: AsRef<[u8]>>(base58: T) -> Result<Self, DigestParseError>

pub const fn next_lexicographical(&self) -> Self

Returns the next digest in byte-increasing order.

pub const fn next_lexicographical_opt(&self) -> Option<Self>

Returns the next digest in byte-increasing order, or None if the result would overflow.

impl TransactionDigest

pub const GENESIS_MARKER: Self = Self::ZERO

A digest used to signify the parent transaction was the genesis. Note that this is not the same as the digest of the genesis transaction, which cannot be known ahead of time.

pub const fn genesis_marker() -> Self

Returns the digest used to signify the parent transaction was the genesis.

Trait Implementations

impl Arbitrary for TransactionDigest
