Struct datastore_grpc::google::datastore::v1::MutationResult

pub struct MutationResult {
    pub key: Option<Key>,
    pub version: i64,
    pub conflict_detected: bool,
}

The result of applying a mutation.

Fields

key: Option<Key>

The automatically allocated key. Set only when the mutation allocated a key.

version: i64

The version of the entity on the server after processing the mutation. If the mutation doesn't change anything on the server, then the version will be the version of the current entity or, if no entity is present, a version that is strictly greater than the version of any previous entity and less than the version of any possible future entity.

conflict_detected: bool

Whether a conflict was detected for this mutation. Always false when a conflict detection strategy field is not set in the mutation.

Trait Implementations

impl Clone for MutationResult

fn clone(&self) -> MutationResult

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for MutationResult

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

Formats the value using the given formatter.

impl Default for MutationResult

fn default() -> Self

Returns the "default value" for a type.

impl Message for MutationResult

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<MutationResult> for MutationResult

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.
