Trait Implementations

impl Clone for TxMock

fn clone(&self) -> TxMock

Returns a copy of the value.

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

Performs copy-assignment from source.

impl DbTx for TxMock

type Cursor<T: Table> = CursorMock

Cursor type for this read-only transaction

type DupCursor<T: DupSort> = CursorMock

DupCursor type for this read-only transaction

fn get<T: Table>(&self, _key: T::Key) -> Result<Option<T::Value>, DatabaseError>

Get value

fn commit(self) -> Result<bool, DatabaseError>

Commit for read only transaction will consume and free transaction and allows freeing of memory pages

fn abort(self)

Aborts transaction

fn cursor_read<T: Table>(&self) -> Result<Self::Cursor<T>, DatabaseError>

Iterate over read only values in table.

fn cursor_dup_read<T: DupSort>( &self, ) -> Result<Self::DupCursor<T>, DatabaseError>

Iterate over read only values in dup sorted table.

fn entries<T: Table>(&self) -> Result<usize, DatabaseError>

Returns number of entries in the table.

fn disable_long_read_transaction_safety(&mut self)

Disables long-lived read transaction safety guarantees.

impl DbTxMut for TxMock

type CursorMut<T: Table> = CursorMock

Read-Write Cursor type

type DupCursorMut<T: DupSort> = CursorMock

Read-Write DupCursor type

fn put<T: Table>( &self, _key: T::Key, _value: T::Value, ) -> Result<(), DatabaseError>

Put value to database

fn delete<T: Table>( &self, _key: T::Key, _value: Option<T::Value>, ) -> Result<bool, DatabaseError>

Delete value from database

fn clear<T: Table>(&self) -> Result<(), DatabaseError>

Clears database.

fn cursor_write<T: Table>(&self) -> Result<Self::CursorMut<T>, DatabaseError>

Cursor mut

fn cursor_dup_write<T: DupSort>( &self, ) -> Result<Self::DupCursorMut<T>, DatabaseError>

DupCursor mut.

impl Debug for TxMock

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

Formats the value using the given formatter.

impl Default for TxMock

fn default() -> TxMock

Returns the “default value” for a type.

impl TableImporter for TxMock

fn import_table<T: Table, R: DbTx>( &self, source_tx: &R, ) -> Result<(), DatabaseError>

Imports all table data from another transaction.

fn import_table_with_range<T: Table, R: DbTx>( &self, source_tx: &R, from: Option<<T as Table>::Key>, to: <T as Table>::Key, ) -> Result<(), DatabaseError>

where T::Key: Default,

Imports table data from another transaction within a range.

fn import_dupsort<T: DupSort, R: DbTx>( &self, source_tx: &R, ) -> Result<(), DatabaseError>

Imports all dupsort data from another transaction.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
