Enum google_api_proto::google::datastore::v1::commit_request::TransactionSelector

pub enum TransactionSelector {
    Transaction(Bytes),
    SingleUseTransaction(TransactionOptions),
}

Must be set when mode is TRANSACTIONAL.

Variants

Transaction(Bytes)

The identifier of the transaction associated with the commit. A transaction identifier is returned by a call to [Datastore.BeginTransaction][google.datastore.v1.Datastore.BeginTransaction].

SingleUseTransaction(TransactionOptions)

Options for beginning a new transaction for this request. The transaction is committed when the request completes. If specified, [TransactionOptions.mode][google.datastore.v1.TransactionOptions] must be [TransactionOptions.ReadWrite][google.datastore.v1.TransactionOptions.ReadWrite].

Implementations

impl TransactionSelector

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

Encodes the message to a buffer.

pub fn merge( field: &mut Option<TransactionSelector>, 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 TransactionSelector

fn clone(&self) -> TransactionSelector

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TransactionSelector

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

Formats the value using the given formatter.

impl PartialEq for TransactionSelector

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