Struct SingleUseReadOnlyTransactionBuilder 

pub struct SingleUseReadOnlyTransactionBuilder { /* private fields */ }

A builder for SingleUseReadOnlyTransaction.

Example

let db_client = spanner.database_client("projects/p/instances/i/databases/d").build().await?;
let read_only_tx = db_client.single_use()
    .set_timestamp_bound(TimestampBound::strong())
    .build();

Implementations

impl SingleUseReadOnlyTransactionBuilder

pub fn set_timestamp_bound(self, bound: TimestampBound) -> Self

Sets the timestamp bound for the read-only transaction.

Example

let db_client = spanner.database_client("projects/p/instances/i/databases/d").build().await?;
let builder = db_client.single_use().set_timestamp_bound(TimestampBound::strong());

When reading data in Spanner in a read-only transaction, you can set a timestamp bound, which tells Spanner how to choose a timestamp at which to read the data.

See https://docs.cloud.google.com/spanner/docs/timestamp-bounds for more information.

pub fn build(self) -> SingleUseReadOnlyTransaction

Builds the SingleUseReadOnlyTransaction.

Example

let db_client = spanner.database_client("projects/p/instances/i/databases/d").build().await?;
let tx = db_client.single_use().build();
