    owner: &Address,
    start: Option<&OwnedTransactionIndexCursor>,
    direction: Option<IterDirection>
) -> impl Iterator<Item = Result<(OwnedTransactionIndexCursor, Bytes32), Error>> + '_

Iterates over a KV mapping of [address + block height + tx idx] => transaction id. This allows for efficient lookup of transaction ids associated with an address, sorted by block age and ordering within a block. The cursor tracks the [block height + tx idx] for pagination purposes.

Trait Implementations

impl AsMut<Database> for DatabaseTransaction

fn as_mut(&mut self) -> &mut Database

Converts this type into a mutable reference of the (usually inferred) input type.

impl AsRef<Database> for DatabaseTransaction

fn as_ref(&self) -> &Database

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for DatabaseTransaction

fn clone(&self) -> DatabaseTransaction

Returns a copy of the value.

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

Performs copy-assignment from source.

impl DatabaseTransaction<Database> for DatabaseTransaction

fn database(&self) -> &Database

Returns the reference to the Database instance.

fn database_mut(&mut self) -> &mut Database

Returns the mutable reference to the Database instance.

impl Debug for DatabaseTransaction

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

Formats the value using the given formatter.

impl Default for DatabaseTransaction

fn default() -> Self

Returns the “default value” for a type.

impl Deref for DatabaseTransaction

type Target = Database

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl DerefMut for DatabaseTransaction

fn deref_mut(&mut self) -> &mut Self::Target

impl Transactional for DatabaseTransaction

fn commit(self) -> Result<()>

Commits the pending state changes into the database.

fn commit_box(self: Box<Self>) -> Result<(), Error>

The same as commit but for case if the value is boxed.
