Struct TransactionId

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

A unique identifier of a transaction.

Transaction ID is computed as:

hash(init_account_commitment, final_account_commitment, input_notes_commitment, output_notes_commitment)

This achieves the following properties:

• Transactions are identical if and only if they have the same ID.
• Computing transaction ID can be done solely from public transaction data.

Implementations

impl TransactionId

pub fn new( init_account_commitment: Digest, final_account_commitment: Digest, input_notes_commitment: Digest, output_notes_commitment: Digest, ) -> Self

Returns a new TransactionId instantiated from the provided transaction components.

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

Returns the elements representation of this transaction ID.

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

Returns the byte representation of this transaction ID.

pub fn to_hex(&self) -> String

Returns a big-endian, hex-encoded string.

pub fn inner(&self) -> Digest

Returns the digest defining this transaction ID.

Trait Implementations

impl Ord for TransactionId

fn cmp(&self, other: &TransactionId) -> 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.

where Self: Sized,

Compares and returns the minimum of two values.

fn eq(&self, other: &TransactionId) -> 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.
