Struct google_api_proto::google::spanner::executor::v1::StartTransactionAction

pub struct StartTransactionAction {
    pub concurrency: Option<Concurrency>,
    pub table: Vec<TableMetadata>,
    pub transaction_seed: String,
    pub execution_options: Option<TransactionExecutionOptions>,
}

StartTransactionAction defines an action of initializing a transaction.

Fields

concurrency: Option<Concurrency>

Concurrency is for read-only transactions and must be omitted for read-write transactions.

table: Vec<TableMetadata>

Metadata about tables and columns that will be involved in this transaction. It is to convert values of key parts correctly.

transaction_seed: String

Transaction_seed contains workid and op pair for this transaction, used for testing.

execution_options: Option<TransactionExecutionOptions>

Execution options (e.g., whether transaction is opaque, optimistic).

Trait Implementations

impl Clone for StartTransactionAction

fn clone(&self) -> StartTransactionAction

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for StartTransactionAction

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

Formats the value using the given formatter.

impl Default for StartTransactionAction

fn default() -> Self

Returns the “default value” for a type.

impl Message for StartTransactionAction

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 StartTransactionAction

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