Struct hedera::TransactionId

pub struct TransactionId {
    pub account_id: AccountId,
    pub valid_start: OffsetDateTime,
    pub nonce: Option<i32>,
    pub scheduled: bool,
}

The client-generated ID for a transaction.

This is used for retrieving receipts and records for a transaction, for appending to a file right after creating it, for instantiating a smart contract with bytecode in a file just created, and internally by the network for detecting when duplicate transactions are submitted.

Fields

account_id: AccountId

The account that pays for this transaction.

valid_start: OffsetDateTime

The time from when this transaction is valid.

When a transaction is submitted there is additionally a valid_duration (defaults to 120s) and together they define a time window that a transaction may be processed in.

nonce: Option<i32>

Nonce for this transaction.

scheduled: bool

true if the transaction is scheduled.

Implementations

impl TransactionId

pub fn generate(account_id: AccountId) -> Self

Generates a new transaction ID for the given account ID.

pub fn from_bytes(bytes: &[u8]) -> Result<Self>

Create a new TransactionId from protobuf-encoded bytes.

Errors

• Error::FromProtobuf if decoding the bytes fails to produce a valid protobuf.
• Error::FromProtobuf if decoding the protobuf fails.

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

Convert self to a protobuf-encoded Vec<u8>.

Trait Implementations

impl Clone for TransactionId

fn clone(&self) -> TransactionId

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TransactionId

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

Formats the value using the given formatter.

impl Display for TransactionId

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

Formats the value using the given formatter.

impl FromStr for TransactionId

type Err = Error

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Hash for TransactionId

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 PartialEq for TransactionId

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