Enum BeginTransactionOption 

#[non_exhaustive]
pub enum BeginTransactionOption {
    InlineBegin,
    ExplicitBegin,
}

Options for how to start a transaction.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

InlineBegin

The transaction will be started inlined with the first statement. This reduces the number of round-trips to Spanner by one.

ExplicitBegin

The transaction will be started explicitly using a BeginTransaction RPC.

Trait Implementations

impl Clone for BeginTransactionOption

fn clone(&self) -> BeginTransactionOption

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for BeginTransactionOption

impl Debug for BeginTransactionOption

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

Formats the value using the given formatter.

impl Default for BeginTransactionOption

fn default() -> BeginTransactionOption

Returns the “default value” for a type.

impl Eq for BeginTransactionOption

impl PartialEq for BeginTransactionOption

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