Struct ledger_mob_core::engine::TxDigest

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

Transaction digest, used to keep a running digest of inputs to the transaction engine to ensure sync between the host and hardware wallet.

Implementations

impl Digest

pub const fn new() -> Digest

Create a new (empty) state digest

pub fn from_random<R>(rng: &mut R) -> Digestwhere R: RngCore + CryptoRng,

Reset state digest from random seed

pub fn update(&mut self, evt: &[u8; 32]) -> &Digest

Update transaction digest with new event

Trait Implementations

impl Clone for Digest

fn clone(&self) -> Digest

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Digest

Debug format Digest as hex

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

Formats the value using the given formatter.

impl DecodeOwned for Digest

Decode Digest into owned array

type Output = Digest

Output type

type Error = Error

Error type returned on parse error

fn decode_owned( buff: &[u8] ) -> Result<(<Digest as DecodeOwned>::Output, usize), <Digest as DecodeOwned>::Error>

Decode consumes a slice and returns an object and decoded length.

impl Display for Digest

Display Digest as hex

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

Formats the value using the given formatter.

impl Encode for Digest

type Error = Error

Error type returned on parse error

fn encode_len(&self) -> Result<usize, <Digest as Encode>::Error>

Calculate expected encoded length for an object

fn encode(&self, buff: &mut [u8]) -> Result<usize, <Digest as Encode>::Error>

Encode method writes object data to the provided writer

impl PartialEq<Digest> for Digest

fn eq(&self, other: &Digest) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
