Struct google_api_proto::google::datastore::v1::MutationResult

pub struct MutationResult {
    pub key: Option<Key>,
    pub version: i64,
    pub create_time: Option<Timestamp>,
    pub update_time: Option<Timestamp>,
    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.

create_time: Option<Timestamp>

The create time of the entity. This field will not be set after a ‘delete’.

update_time: Option<Timestamp>

The update time of the entity on the server after processing the mutation. If the mutation doesn’t change anything on the server, then the timestamp will be the update timestamp of the current entity. This field will not be set after a ‘delete’.

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.

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 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 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: &Rhs) -> bool

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