Enum Transaction

pub enum Transaction {
    TransactionId(Vec<u8>),
    SingleUseTransaction(TransactionOptions),
}

Required. The transaction in which to commit.

Variants

TransactionId(Vec<u8>)

Commit a previously-started transaction.

SingleUseTransaction(TransactionOptions)

Execute mutations in a temporary transaction. Note that unlike commit of a previously-started transaction, commit with a temporary transaction is non-idempotent. That is, if the CommitRequest is sent to Cloud Spanner more than once (for instance, due to retries in the application, or in the transport library), it is possible that the mutations are executed more than once. If this is undesirable, use [BeginTransaction][google.spanner.v1.Spanner.BeginTransaction] and [Commit][google.spanner.v1.Spanner.Commit] instead.

Implementations

impl Transaction

pub fn encode<B>(&self, buf: &mut B)

where B: BufMut,

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

where B: Buf,

pub fn encoded_len(&self) -> usize

Trait Implementations

impl Clone for Transaction

fn clone(&self) -> Transaction

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Transaction

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

Formats the value using the given formatter.

impl PartialEq for Transaction

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