Struct google_api_proto::google::datastore::v1::AggregationResultBatch

pub struct AggregationResultBatch {
    pub aggregation_results: Vec<AggregationResult>,
    pub more_results: i32,
    pub read_time: Option<Timestamp>,
}

A batch of aggregation results produced by an aggregation query.

Fields

aggregation_results: Vec<AggregationResult>

The aggregation results for this batch.

more_results: i32

The state of the query after the current batch. Only COUNT(*) aggregations are supported in the initial launch. Therefore, expected result type is limited to NO_MORE_RESULTS.

read_time: Option<Timestamp>

Read timestamp this batch was returned from.

In a single transaction, subsequent query result batches for the same query can have a greater timestamp. Each batch’s read timestamp is valid for all preceding batches.

Implementations

impl AggregationResultBatch

pub fn more_results(&self) -> MoreResultsType

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

pub fn set_more_results(&mut self, value: MoreResultsType)

Sets more_results to the provided enum value.

Trait Implementations

impl Clone for AggregationResultBatch

fn clone(&self) -> AggregationResultBatch

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for AggregationResultBatch

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

Formats the value using the given formatter.

impl Default for AggregationResultBatch

fn default() -> Self

Returns the “default value” for a type.

impl Message for AggregationResultBatch

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 AggregationResultBatch

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