Struct Write 

pub struct Write { /* private fields */ }

A client for BigQuery Storage Write API.

Implementations

impl Write

pub fn builder() -> ClientBuilder

Creates a new ClientBuilder.

pub fn open_default_stream<T: Into<String>>( &self, table: T, ) -> WriterBuilder<DefaultStream>

Opens the default stream for the given table.

Example

let writer = client
    .open_default_stream("projects/my-project/datasets/my-dataset/tables/my-table")
    .build_arrow(schema())
    .await?;

use google_cloud_bigquery::model::ArrowSchema;
fn schema() -> ArrowSchema {
  todo!("Define your table's schema...")
}

pub fn create_stream<S: ApplicationCreatedStream, T: Into<String>>( &self, table: T, ) -> WriterBuilder<S>

Creates a new application-created stream for the given table.

The stream type S can be inferred from the variable’s writer type annotation (PendingWriter, CommittedWriter, or BufferedWriter) or specified explicitly via turbofish (create_stream::<PendingStream, _>(...)).

Example

use google_cloud_bigquery::write::PendingWriter;
use google_cloud_bigquery::write::format::Arrow;
let writer: PendingWriter<Arrow> = client
    .create_stream("projects/my-project/datasets/my-dataset/tables/my-table")
    .build_arrow(schema())
    .await?;

use google_cloud_bigquery::model::ArrowSchema;
fn schema() -> ArrowSchema {
  todo!("Define your table's schema...")
}

pub fn attach_to_stream<S: ApplicationCreatedStream, T: Into<String>>( &self, write_stream: T, ) -> WriterBuilder<S>

Attaches to an existing application-created stream.

The stream type S can be inferred from the variable’s writer type annotation (PendingWriter, CommittedWriter, or BufferedWriter) or specified explicitly via turbofish (attach_to_stream::<PendingStream, _>(...)).

Example

use google_cloud_bigquery::write::CommittedWriter;
use google_cloud_bigquery::write::format::Arrow;
let writer: CommittedWriter<Arrow> = client
    .attach_to_stream("projects/my-project/datasets/my_dataset/tables/my_table/streams/my_stream")
    .build_arrow(schema())
    .await?;
