Struct AccountUpdateWitness

pub struct AccountUpdateWitness { /* private fields */ }

This type encapsulates essentially three components:

• The initial and final state commitment of the account update.
• The witness is an smt proof of the initial state commitment of the account before the block in which the witness is included, that is, in the account tree at the state of the previous block header.
• The account update details represent the delta between the state of the account before the block and the state after this block.

Implementations

impl AccountUpdateWitness

pub fn new( initial_state_commitment: Digest, final_state_commitment: Digest, initial_state_proof: AccountWitness, details: AccountUpdateDetails, ) -> Self

Constructs a new, partial AccountUpdateWitness from the provided parts.

pub fn initial_state_commitment(&self) -> Digest

Returns the initial state commitment of the account.

pub fn final_state_commitment(&self) -> Digest

Returns the final state commitment of the account.

pub fn as_witness(&self) -> &AccountWitness

Returns a reference to the initial state proof of the account.

pub fn to_witness(&self) -> AccountWitness

Returns the AccountWitness of this update witness.

pub fn details(&self) -> &AccountUpdateDetails

Returns a reference to the underlying AccountUpdateDetails of this update, representing the state transition of the account from the previous block to the block this witness is for.

pub fn initial_state_proof_mut(&mut self) -> &mut AccountWitness

Returns a mutable reference to the initial state proof of the account.

pub fn into_parts( self, ) -> (Digest, Digest, AccountWitness, AccountUpdateDetails)

Consumes self and returns its parts.

Trait Implementations

impl Clone for AccountUpdateWitness

fn clone(&self) -> AccountUpdateWitness

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AccountUpdateWitness

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

Formats the value using the given formatter.

impl Deserializable for AccountUpdateWitness

fn read_from<R: ByteReader>( source: &mut R, ) -> Result<Self, DeserializationError>

Reads a sequence of bytes from the provided source, attempts to deserialize these bytes into Self, and returns the result.

fn read_from_bytes(bytes: &[u8]) -> Result<Self, DeserializationError>

Attempts to deserialize the provided bytes into Self and returns the result.

impl PartialEq for AccountUpdateWitness

fn eq(&self, other: &AccountUpdateWitness) -> 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 Serializable for AccountUpdateWitness

fn write_into<W: ByteWriter>(&self, target: &mut W)

Serializes self into bytes and writes these bytes into the target.

fn to_bytes(&self) -> Vec<u8>

Serializes self into a vector of bytes.

fn get_size_hint(&self) -> usize

Returns an estimate of how many bytes are needed to represent self.
