Struct Transaction 

pub struct Transaction {
    pub id: Option<Vec<u8>>,
    pub precommit_token: Option<MultiplexedSessionPrecommitToken>,
    pub read_timestamp: Option<DateTime<Utc>>,
}

A transaction.

Activities

This type is used in activities, which are methods you may call on this type or where this type is involved in. The list links the activity name, along with information about where it is used (one of request and response).

• instances databases sessions begin transaction projects (response)

Fields

id: Option<Vec<u8>>

id may be used to identify the transaction in subsequent Read, ExecuteSql, Commit, or Rollback calls. Single-use read-only transactions do not have IDs, because single-use transactions do not support multiple requests.

precommit_token: Option<MultiplexedSessionPrecommitToken>

A precommit token is included in the response of a BeginTransaction request if the read-write transaction is on a multiplexed session and a mutation_key was specified in the BeginTransaction. The precommit token with the highest sequence number from this transaction attempt should be passed to the Commit request for this transaction.

read_timestamp: Option<DateTime<Utc>>

For snapshot read-only transactions, the read timestamp chosen for the transaction. Not returned by default: see TransactionOptions.ReadOnly.return_read_timestamp. A timestamp in RFC3339 UTC "Zulu" format, accurate to nanoseconds. Example: "2014-10-02T15:01:23.045123456Z".
