RocksTx

Struct RocksTx 

Source
pub struct RocksTx<'db> { /* private fields */ }
Expand description

RocksDB transaction wrapper providing MDBX-like semantics.

Supports:

  • Read-your-writes: reads see uncommitted writes within the same transaction
  • Atomic commit/rollback
  • Iteration over uncommitted data

Note: Transaction is Send but NOT Sync. This wrapper does not implement DbTx/DbTxMut traits directly; use RocksDB-specific methods instead.

Implementations§

Source§

impl<'db> RocksTx<'db>

Source

pub fn get<T: Table>(&self, key: T::Key) -> ProviderResult<Option<T::Value>>

Gets a value from the specified table. Sees uncommitted writes in this transaction.

Source

pub fn get_encoded<T: Table>( &self, key: &<T::Key as Encode>::Encoded, ) -> ProviderResult<Option<T::Value>>

Gets a value using pre-encoded key. Sees uncommitted writes in this transaction.

Source

pub fn put<T: Table>(&self, key: T::Key, value: &T::Value) -> ProviderResult<()>

Puts a value into the specified table.

Source

pub fn put_encoded<T: Table>( &self, key: &<T::Key as Encode>::Encoded, value: &T::Value, ) -> ProviderResult<()>

Puts a value using pre-encoded key.

Source

pub fn delete<T: Table>(&self, key: T::Key) -> ProviderResult<()>

Deletes a value from the specified table.

Source

pub fn iter<T: Table>(&self) -> ProviderResult<RocksTxIter<'_, T>>

Creates an iterator for the specified table. Sees uncommitted writes in this transaction.

Returns an iterator that yields (encoded_key, compressed_value) pairs.

Source

pub fn iter_from<T: Table>( &self, key: T::Key, ) -> ProviderResult<RocksTxIter<'_, T>>

Creates an iterator starting from the given key (inclusive).

Source

pub fn commit(self) -> ProviderResult<()>

Commits the transaction, persisting all changes.

Source

pub fn rollback(self) -> ProviderResult<()>

Rolls back the transaction, discarding all changes.
