Struct datastore_grpc::google::datastore::v1beta3::TransactionOptions

pub struct TransactionOptions {
    pub mode: Option<Mode>,
}

Options for beginning a new transaction.

Transactions can be created explicitly with calls to [Datastore.BeginTransaction][google.datastore.v1beta3.Datastore.BeginTransaction] or implicitly by setting [ReadOptions.new_transaction][google.datastore.v1beta3.ReadOptions.new_transaction] in read requests.

Fields

mode: Option<Mode>

The mode of the transaction, indicating whether write operations are supported.

Trait Implementations

impl Clone for TransactionOptions

fn clone(&self) -> TransactionOptions

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TransactionOptions

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

Formats the value using the given formatter.

impl Default for TransactionOptions

fn default() -> Self

Returns the "default value" for a type.

impl Message for TransactionOptions

fn encode_raw<B>(&self, buf: &mut B) where
    B: BufMut, 

fn merge_field<B>(
    &mut self,
    tag: u32,
    wire_type: WireType,
    buf: &mut B,
    ctx: DecodeContext
) -> Result<(), DecodeError> where
    B: Buf, 

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.

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

Encodes the message to a buffer.

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

Encodes the message with a length-delimiter to a buffer.

pub fn decode<B>(buf: B) -> Result<Self, DecodeError> where
    Self: Default,
    B: Buf, 

Decodes an instance of the message from a buffer.

pub fn decode_length_delimited<B>(buf: B) -> Result<Self, DecodeError> where
    Self: Default,
    B: Buf, 

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

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

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

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

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

impl PartialEq<TransactionOptions> for TransactionOptions

fn eq(&self, other: &TransactionOptions) -> bool
