Enum google_api_proto::google::spanner::v1::transaction_options::Mode

pub enum Mode {
    ReadWrite(ReadWrite),
    PartitionedDml(PartitionedDml),
    ReadOnly(ReadOnly),
}

Required. The type of transaction.

Variants

ReadWrite(ReadWrite)

Transaction may write.

Authorization to begin a read-write transaction requires spanner.databases.beginOrRollbackReadWriteTransaction permission on the session resource.

PartitionedDml(PartitionedDml)

Partitioned DML transaction.

Authorization to begin a Partitioned DML transaction requires spanner.databases.beginPartitionedDmlTransaction permission on the session resource.

ReadOnly(ReadOnly)

Transaction will not write.

Authorization to begin a read-only transaction requires spanner.databases.beginReadOnlyTransaction permission on the session resource.

Implementations

impl Mode

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

Encodes the message to a buffer.

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

fn clone(&self) -> Mode

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Mode

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

Formats the value using the given formatter.

impl PartialEq for Mode

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