Struct google_api_proto::google::spanner::v1::ExecuteBatchDmlRequest

pub struct ExecuteBatchDmlRequest {
    pub session: String,
    pub transaction: Option<TransactionSelector>,
    pub statements: Vec<Statement>,
    pub seqno: i64,
    pub request_options: Option<RequestOptions>,
}

The request for [ExecuteBatchDml][google.spanner.v1.Spanner.ExecuteBatchDml].

Fields

session: String

Required. The session in which the DML statements should be performed.

transaction: Option<TransactionSelector>

Required. The transaction to use. Must be a read-write transaction.

To protect against replays, single-use transactions are not supported. The caller must either supply an existing transaction ID or begin a new transaction.

statements: Vec<Statement>

Required. The list of statements to execute in this batch. Statements are executed serially, such that the effects of statement i are visible to statement i+1. Each statement must be a DML statement. Execution stops at the first failed statement; the remaining statements are not executed.

Callers must provide at least one statement.

seqno: i64

Required. A per-transaction sequence number used to identify this request. This field makes each request idempotent such that if the request is received multiple times, at most one will succeed.

The sequence number must be monotonically increasing within the transaction. If a request arrives for the first time with an out-of-order sequence number, the transaction may be aborted. Replays of previously handled requests will yield the same response as the first execution.

request_options: Option<RequestOptions>

Common options for this request.

Trait Implementations

impl Clone for ExecuteBatchDmlRequest

fn clone(&self) -> ExecuteBatchDmlRequest

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ExecuteBatchDmlRequest

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

Formats the value using the given formatter.

impl Default for ExecuteBatchDmlRequest

fn default() -> Self

Returns the “default value” for a type.

impl Message for ExecuteBatchDmlRequest

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<B>(&self, buf: &mut B) -> Result<(), EncodeError>

where B: BufMut, 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<B>(&self, buf: &mut B) -> Result<(), EncodeError>

where B: BufMut, 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<B>(buf: B) -> Result<Self, DecodeError>

where B: Buf, Self: Default,

Decodes an instance of the message from a buffer.

fn decode_length_delimited<B>(buf: B) -> Result<Self, DecodeError>

where B: Buf, Self: Default,

Decodes a length-delimited instance of the message from the buffer.

fn merge<B>(&mut self, buf: B) -> Result<(), DecodeError>

where B: Buf, Self: Sized,

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

fn merge_length_delimited<B>(&mut self, buf: B) -> Result<(), DecodeError>

where B: Buf, Self: Sized,

Decodes a length-delimited instance of the message from buffer, and merges it into self.

impl PartialEq for ExecuteBatchDmlRequest

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