Struct google_api_proto::google::spanner::executor::v1::GenerateDbPartitionsForReadAction

pub struct GenerateDbPartitionsForReadAction {
    pub read: Option<ReadAction>,
    pub table: Vec<TableMetadata>,
    pub desired_bytes_per_partition: Option<i64>,
    pub max_partition_count: Option<i64>,
}

Generate database partitions for the given read. Successful outcomes will contain database partitions in the db_partition field.

Fields

read: Option<ReadAction>

Read to generate partitions for.

table: Vec<TableMetadata>

Metadata related to the tables involved in the read.

desired_bytes_per_partition: Option<i64>

Desired size of data in each partition. Spanner doesn’t guarantee to respect this value.

max_partition_count: Option<i64>

If set, the desired max number of partitions. Spanner doesn’t guarantee to respect this value.

Implementations

impl GenerateDbPartitionsForReadAction

pub fn desired_bytes_per_partition(&self) -> i64

Returns the value of desired_bytes_per_partition, or the default value if desired_bytes_per_partition is unset.

pub fn max_partition_count(&self) -> i64

Returns the value of max_partition_count, or the default value if max_partition_count is unset.

Trait Implementations

impl Clone for GenerateDbPartitionsForReadAction

fn clone(&self) -> GenerateDbPartitionsForReadAction

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for GenerateDbPartitionsForReadAction

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

Formats the value using the given formatter.

impl Default for GenerateDbPartitionsForReadAction

fn default() -> Self

Returns the “default value” for a type.

impl Message for GenerateDbPartitionsForReadAction

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 GenerateDbPartitionsForReadAction

fn eq(&self, other: &GenerateDbPartitionsForReadAction) -> 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.
