Struct gapi_grpc::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.

pub 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() -> ReadSession

Returns the “default value” for a type.

impl Message for ReadSession

fn encode_raw<B>(&self, buf: &mut B) where
    B: BufMut, 

fn merge_field<B>(
    &mut self,
    tag: u32,
    wire_type: WireType,
    buf: &mut B,
    ctx: DecodeContext
) -> Result<(), DecodeError> where
    B: Buf, 

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.

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

Encodes the message to a buffer.

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

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

pub fn decode<B>(buf: B) -> Result<Self, DecodeError> where
    Self: Default,
    B: Buf, 

Decodes an instance of the message from a buffer.

pub fn decode_length_delimited<B>(buf: B) -> Result<Self, DecodeError> where
    Self: Default,
    B: Buf, 

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

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

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

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

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

impl PartialEq<ReadSession> 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: &ReadSession) -> bool

This method tests for !=.
