Struct google_api_proto::google::datastore::v1::QueryResultBatch

pub struct QueryResultBatch {
    pub skipped_results: i32,
    pub skipped_cursor: Bytes,
    pub entity_result_type: i32,
    pub entity_results: Vec<EntityResult>,

    pub snapshot_version: i64,
    pub read_time: Option<Timestamp>,
}

A batch of results produced by a query.

Fields

skipped_results: i32

The number of results skipped, typically because of an offset.

skipped_cursor: Bytes

A cursor that points to the position after the last skipped result. Will be set when skipped_results != 0.

entity_result_type: i32

The result type for every entity in entity_results.

entity_results: Vec<EntityResult>

The results for this batch.

end_cursor: Bytes

A cursor that points to the position after the last result in the batch.

more_results: i32

The state of the query after the current batch.

snapshot_version: i64

The version number of the snapshot this batch was returned from. This applies to the range of results from the query’s start_cursor (or the beginning of the query if no cursor was given) to this batch’s end_cursor (not the query’s end_cursor).

In a single transaction, subsequent query result batches for the same query can have a greater snapshot version number. Each batch’s snapshot version is valid for all preceding batches. The value will be zero for eventually consistent queries.

read_time: Option<Timestamp>

Read timestamp this batch was returned from. This applies to the range of results from the query’s start_cursor (or the beginning of the query if no cursor was given) to this batch’s end_cursor (not the query’s end_cursor).

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. This value will not be set for eventually consistent queries in Cloud Datastore.

Implementations

impl QueryResultBatch

pub fn entity_result_type(&self) -> ResultType

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

pub fn set_entity_result_type(&mut self, value: ResultType)

Sets entity_result_type to the provided enum value.

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 QueryResultBatch

fn clone(&self) -> QueryResultBatch

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for QueryResultBatch

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

Formats the value using the given formatter.

impl Default for QueryResultBatch

fn default() -> Self

Returns the “default value” for a type.

impl Message for QueryResultBatch

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<B>(&self, buf: &mut B) -> Result<(), EncodeError>

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

where B: BufMut, 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<B>(buf: B) -> Result<Self, DecodeError>

where B: Buf, Self: Default,

Decodes an instance of the message from a buffer.

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

where B: Buf, Self: Default,

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

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

where B: Buf, Self: Sized,

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

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

where B: Buf, Self: Sized,

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

impl PartialEq for QueryResultBatch

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