Struct Transaction 

#[non_exhaustive]
pub struct Transaction {
    pub update_id: String,
    pub command_id: String,
    pub workflow_id: String,
    pub offset: i64,
    pub synchronizer_id: String,
    pub effective_at: Option<Timestamp>,
    pub record_time: Option<Timestamp>,
    pub events: Vec<Event>,
}

A committed transaction.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

update_id: String

The update id.

command_id: String

The command id, visible to the submitting parties only.

workflow_id: String

The workflow id, if one was set.

offset: i64

The ledger offset.

synchronizer_id: String

The synchronizer the transaction was committed on.

effective_at: Option<Timestamp>

Ledger effective time.

record_time: Option<Timestamp>

The synchronizer’s record time.

events: Vec<Event>

The events visible to the subscribed parties, in node order.

Implementations

impl Transaction

pub fn from_grpc(tx: Transaction) -> Result<Self>

A gRPC transaction, as a stream, a point read or submit-and-wait returns it.

Errors

Error::UnexpectedResponse if an event is malformed.

pub fn from_json(tx: &Value) -> Result<Self>

A JSON transaction (the value of a Transaction update, or the transaction of a submit-and-wait-for-transaction response).

Errors

Error::UnexpectedResponse if a field is malformed.

pub fn created(&self) -> impl Iterator<Item = &CreatedEvent>

The created events.

pub fn archived(&self) -> impl Iterator<Item = &ArchivedEvent>

The archived events.

pub fn exercised(&self) -> impl Iterator<Item = &ExercisedEvent>

The exercised events (present under the ledger-effects shape).

Trait Implementations

impl Clone for Transaction

fn clone(&self) -> Self

Returns a duplicate 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.
