Enum TransactionState 

pub enum TransactionState {
    Empty,
    Ongoing,
    PrepareCommit,
    PrepareAbort,
    CompleteCommit,
    CompleteAbort,
    Dead,
}

Transaction state machine

Variants

Empty

No active transaction

Ongoing

Transaction in progress, accepting writes

PrepareCommit

Preparing to commit (2PC phase 1)

PrepareAbort

Preparing to abort (2PC phase 1)

CompleteCommit

Commit complete (2PC phase 2)

CompleteAbort

Abort complete (2PC phase 2)

Dead

Transaction has expired without completion

Implementations

impl TransactionState

pub fn is_terminal(&self) -> bool

Check if transaction is in a terminal state

pub fn is_active(&self) -> bool

Check if transaction is still active (can accept writes)

pub fn can_commit(&self) -> bool

Check if transaction can transition to commit

pub fn can_abort(&self) -> bool

Check if transaction can transition to abort

Trait Implementations

impl Clone for TransactionState

fn clone(&self) -> TransactionState

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TransactionState

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for TransactionState

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for TransactionState

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

impl Serialize for TransactionState

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for TransactionState

impl Eq for TransactionState
