Struct InMemoryTransaction 

pub struct InMemoryTransaction<S: Snapshotable> { /* private fields */ }

Pure-in-memory transaction. Snapshots the source via Snapshotable::snapshot on begin, restores via Snapshotable::restore on rollback.

Implementations

impl<S: Snapshotable> InMemoryTransaction<S>

pub fn begin(source: S) -> Self

pub fn active(&self) -> bool

pub fn commit(&mut self) -> TxResult<()>

pub fn rollback(&mut self) -> TxResult<()>

pub fn savepoint(&mut self, name: impl Into<String>) -> TxResult<()>

pub fn release_savepoint(&mut self, name: &str) -> TxResult<()>

pub fn rollback_to(&mut self, name: &str) -> TxResult<()>

Trait Implementations

impl<S: Snapshotable> Drop for InMemoryTransaction<S>

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
