Struct Transaction

pub struct Transaction {
    pub app_id: String,
    pub version: i64,
    pub last_updated: Option<i64>,
}

Action used by streaming systems to track progress using application-specific versions to enable idempotency.

Fields

app_id: String

A unique identifier for the application performing the transaction.

version: i64

An application-specific numeric identifier for this transaction.

last_updated: Option<i64>

The time when this transaction action was created in milliseconds since the Unix epoch.

Implementations

impl Transaction

pub fn new(app_id: impl ToString, version: i64) -> Self

Create a new application transactions. See [Txn] for details.

pub fn new_with_last_update( app_id: impl ToString, version: i64, last_updated: Option<i64>, ) -> Self

Create a new application transactions. See [Txn] for details.

Trait Implementations

impl Clone for Transaction

fn clone(&self) -> Transaction

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Transaction

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

Formats the value using the given formatter.

impl Default for Transaction

fn default() -> Transaction

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Transaction

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<Transaction> for Action

fn from(a: Transaction) -> Self

Converts to this type from the input type.

impl PartialEq for Transaction

fn eq(&self, other: &Transaction) -> 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 Serialize for Transaction

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for Transaction
