Struct TransactionOptions 

#[non_exhaustive]
pub struct TransactionOptions {
    pub exclude_txn_from_change_streams: bool,
    pub isolation_level: IsolationLevel,
    pub mode: Option<Mode>,
    /* private fields */
}

Options to use for transactions.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

exclude_txn_from_change_streams: bool

When exclude_txn_from_change_streams is set to true, it prevents read or write transactions from being tracked in change streams.

• If the DDL option allow_txn_exclusion is set to true, then the updates made within this transaction aren’t recorded in the change stream.

• If you don’t set the DDL option allow_txn_exclusion or if it’s set to false, then the updates made within this transaction are recorded in the change stream.

When exclude_txn_from_change_streams is set to false or not set, modifications from this transaction are recorded in all change streams that are tracking columns modified by these transactions.

The exclude_txn_from_change_streams option can only be specified for read-write or partitioned DML transactions, otherwise the API returns an INVALID_ARGUMENT error.

isolation_level: IsolationLevel

Isolation level for the transaction.

mode: Option<Mode>

Required. The type of transaction.

Implementations

impl TransactionOptions

pub fn new() -> Self

Creates a new default instance.

pub fn set_exclude_txn_from_change_streams<T: Into<bool>>(self, v: T) -> Self

Sets the value of exclude_txn_from_change_streams.

pub fn set_isolation_level<T: Into<IsolationLevel>>(self, v: T) -> Self

Sets the value of isolation_level.

pub fn set_mode<T: Into<Option<Mode>>>(self, v: T) -> Self

Sets the value of mode.

Note that all the setters affecting mode are mutually exclusive.

pub fn read_write(&self) -> Option<&Box<ReadWrite>>

The value of mode if it holds a ReadWrite, None if the field is not set or holds a different branch.

pub fn set_read_write<T: Into<Box<ReadWrite>>>(self, v: T) -> Self

Sets the value of mode to hold a ReadWrite.

Note that all the setters affecting mode are mutually exclusive.

pub fn partitioned_dml(&self) -> Option<&Box<PartitionedDml>>

The value of mode if it holds a PartitionedDml, None if the field is not set or holds a different branch.

pub fn set_partitioned_dml<T: Into<Box<PartitionedDml>>>(self, v: T) -> Self

Sets the value of mode to hold a PartitionedDml.

Note that all the setters affecting mode are mutually exclusive.

pub fn read_only(&self) -> Option<&Box<ReadOnly>>

The value of mode if it holds a ReadOnly, None if the field is not set or holds a different branch.

pub fn set_read_only<T: Into<Box<ReadOnly>>>(self, v: T) -> Self

Sets the value of mode to hold a ReadOnly.

Note that all the setters affecting mode are mutually exclusive.

Trait Implementations

impl Clone for TransactionOptions

fn clone(&self) -> TransactionOptions

Returns a duplicate of the value.

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() -> TransactionOptions

Returns the “default value” for a type.

impl Message for TransactionOptions

fn typename() -> &'static str

The typename of this message.

impl PartialEq for TransactionOptions

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

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
