Enum google_api_proto::google::datastore::v1::mutation::ConflictDetectionStrategy

pub enum ConflictDetectionStrategy {
    BaseVersion(i64),
    UpdateTime(Timestamp),
}

When set, the server will detect whether or not this mutation conflicts with the current version of the entity on the server. Conflicting mutations are not applied, and are marked as such in MutationResult.

Variants

BaseVersion(i64)

The version of the entity that this mutation is being applied to. If this does not match the current version on the server, the mutation conflicts.

UpdateTime(Timestamp)

The update time of the entity that this mutation is being applied to. If this does not match the current update time on the server, the mutation conflicts.

Implementations

impl ConflictDetectionStrategy

pub fn encode(&self, buf: &mut impl BufMut)

Encodes the message to a buffer.

pub fn merge( field: &mut Option<ConflictDetectionStrategy>, tag: u32, wire_type: WireType, buf: &mut impl Buf, ctx: DecodeContext, ) -> Result<(), DecodeError>

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

pub fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

Trait Implementations

impl Clone for ConflictDetectionStrategy

fn clone(&self) -> ConflictDetectionStrategy

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ConflictDetectionStrategy

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

Formats the value using the given formatter.

impl PartialEq for ConflictDetectionStrategy

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