Struct Transaction 

pub struct Transaction<'a> { /* private fields */ }

Write-through transactional context for ACID operations

Implementations

impl Transaction<'_>

pub fn set(&mut self, key: &[u8], value: Vec<u8>) -> Result<()>

Sets a key-value pair directly in the engine with undo logging

pub fn delete(&mut self, key: &[u8]) -> Result<()>

Deletes a key directly in the engine with undo logging

pub fn get(&self, key: &[u8]) -> Option<Rc<[u8]>>

Retrieves a value directly from the engine (no transaction-local state)

pub fn scan( &self, range: Range<Vec<u8>>, ) -> Result<Box<dyn Iterator<Item = (Vec<u8>, Rc<[u8]>)> + '_>>

Scans a range directly from the engine (no transaction-local state)

pub fn has_pending_operations(&self) -> bool

Returns true if the transaction has pending operations (i.e., uncommitted changes)

pub fn is_clean(&self) -> bool

Returns true if the transaction is clean (no pending operations)

pub fn is_finalized(&self) -> bool

Returns true if the transaction has been finalized (committed or rolled back)

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

Commits the transaction by writing commit marker

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

Rolls back the transaction by restoring original values

Trait Implementations

impl Drop for Transaction<'_>

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.
