Struct BatchId 

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

Uniquely identifies a batch of transactions, i.e. both ProposedBatch and ProvenBatch.

This is a sequential hash of the tuple (TRANSACTION_ID || [account_id_prefix, account_id_suffix, 0, 0]) of all transactions and the accounts their executed against in the batch.

Implementations

impl BatchId

pub fn from_transactions<'tx, T>(txs: T) -> Self

where T: Iterator<Item = &'tx ProvenTransaction>,

Calculates a batch ID from the given set of transactions.

pub fn from_ids( iter: impl IntoIterator<Item = (TransactionId, AccountId)>, ) -> Self

Calculates a batch ID from the given transaction ID and account ID tuple.

pub fn as_elements(&self) -> &[Felt]

Returns the elements representation of this batch ID.

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

Returns the byte representation of this batch ID.

pub fn to_hex(&self) -> String

Returns a big-endian, hex-encoded string.

Trait Implementations

impl Clone for BatchId

fn clone(&self) -> BatchId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BatchId

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

Formats the value using the given formatter.

impl Deserializable for BatchId

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 Display for BatchId

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

Formats the value using the given formatter.

impl Hash for BatchId

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 Ord for BatchId

fn cmp(&self, other: &BatchId) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for BatchId

fn eq(&self, other: &BatchId) -> 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 PartialOrd for BatchId

fn partial_cmp(&self, other: &BatchId) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serializable for BatchId

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.
