Struct google_api_proto::google::cloud::bigquery::storage::v1beta1::ReadSession

pub struct ReadSession {
    pub name: String,
    pub expire_time: Option<Timestamp>,
    pub streams: Vec<Stream>,
    pub table_reference: Option<TableReference>,
    pub table_modifiers: Option<TableModifiers>,
    pub sharding_strategy: i32,
    pub schema: Option<Schema>,
}

Information returned from a CreateReadSession request.

Fields

name: String

Unique identifier for the session, in the form projects/{project_id}/locations/{location}/sessions/{session_id}.

expire_time: Option<Timestamp>

Time at which the session becomes invalid. After this time, subsequent requests to read this Session will return errors.

streams: Vec<Stream>

Streams associated with this session.

table_reference: Option<TableReference>

Table that this ReadSession is reading from.

table_modifiers: Option<TableModifiers>

Any modifiers which are applied when reading from the specified table.

sharding_strategy: i32

The strategy to use for distributing data among the streams.

schema: Option<Schema>

The schema for the read. If read_options.selected_fields is set, the schema may be different from the table schema as it will only contain the selected fields.

Implementations

impl ReadSession

pub fn sharding_strategy(&self) -> ShardingStrategy

Returns the enum value of sharding_strategy, or the default if the field is set to an invalid enum value.

pub fn set_sharding_strategy(&mut self, value: ShardingStrategy)

Sets sharding_strategy to the provided enum value.

Trait Implementations

impl Clone for ReadSession

fn clone(&self) -> ReadSession

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ReadSession

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

Formats the value using the given formatter.

impl Default for ReadSession

fn default() -> Self

Returns the “default value” for a type.

impl Message for ReadSession

fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn encode(&self, buf: &mut impl BufMut) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message to a buffer.

fn encode_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message to a newly allocated buffer.

fn encode_length_delimited( &self, buf: &mut impl BufMut, ) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message with a length-delimiter to a buffer.

fn encode_length_delimited_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message with a length-delimiter to a newly allocated buffer.

fn decode(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes an instance of the message from a buffer.

fn decode_length_delimited(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes a length-delimited instance of the message from the buffer.

fn merge(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes an instance of the message from a buffer, and merges it into self.

fn merge_length_delimited(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes a length-delimited instance of the message from buffer, and merges it into self.

impl PartialEq for ReadSession

fn eq(&self, other: &ReadSession) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
