Struct EntityResult

pub struct EntityResult {
    pub entity: Option<Entity>,
    pub version: i64,
    pub cursor: Vec<u8>,
}

The result of fetching an entity from Datastore.

Fields

entity: Option<Entity>

The resulting entity.

version: i64

The version of the entity, a strictly positive number that monotonically increases with changes to the entity.

This field is set for [FULL][google.datastore.v1.EntityResult.ResultType.FULL] entity results.

For [missing][google.datastore.v1.LookupResponse.missing] entities in LookupResponse, this is the version of the snapshot that was used to look up the entity, and it is always set except for eventually consistent reads.

cursor: Vec<u8>

A cursor that points to the position after the result entity. Set only when the EntityResult is part of a QueryResultBatch message.

Trait Implementations

impl Clone for EntityResult

fn clone(&self) -> EntityResult

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EntityResult

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

Formats the value using the given formatter.

impl Default for EntityResult

fn default() -> EntityResult

Returns the “default value” for a type.

impl Message for EntityResult

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_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 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 EntityResult

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

Tests for self and other values to be equal, and is used by ==.

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

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