Enum google_api_proto::google::spanner::executor::v1::start_batch_transaction_action::Param

pub enum Param {
    BatchTxnTime(Timestamp),
    Tid(Bytes),
}

To start a new transaction, specify an exact timestamp. Alternatively, an existing batch transaction ID can be used. Either one of two must be set.

Variants

BatchTxnTime(Timestamp)

The exact timestamp to start the batch transaction.

Tid(Bytes)

ID of a batch read-only transaction. It can be used to start the same batch transaction on multiple executors and parallelize partition processing.

Implementations

impl Param

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

Encodes the message to a buffer.

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

fn clone(&self) -> Param

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Param

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

Formats the value using the given formatter.

impl PartialEq for Param

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