Struct TransactionLifecycle 

pub struct TransactionLifecycle { /* private fields */ }

A small state machine shared by storage-backed domain transactions.

Implementations

impl TransactionLifecycle

pub fn new() -> Self

Creates a new open transaction with a stable identity.

pub const fn with_id(id: TransactionId) -> Self

Creates an open transaction with an existing identity.

pub const fn id(self) -> TransactionId

Returns the transaction identity.

pub const fn state(self) -> TransactionState

Returns the current state.

pub fn ensure_open(self) -> Result<()>

Ensures that a mutation may be staged.

Errors

Returns ErrorKind::Conflict if the transaction is already closed.

pub fn mark_committed(&mut self) -> Result<()>

Marks the transaction committed after the backend commit succeeds.

Errors

Returns ErrorKind::Conflict if the transaction is already closed.

pub fn mark_rolled_back(&mut self) -> Result<()>

Marks the transaction rolled back after staged work is discarded.

Errors

Returns ErrorKind::Conflict if the transaction is already closed.

Trait Implementations

impl Clone for TransactionLifecycle

fn clone(&self) -> TransactionLifecycle

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for TransactionLifecycle

impl Debug for TransactionLifecycle

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

Formats the value using the given formatter.

impl Default for TransactionLifecycle

fn default() -> Self

Returns the “default value” for a type.

impl Eq for TransactionLifecycle

impl PartialEq for TransactionLifecycle

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