Provided Methods§
Sourcefn import_table<T: Table, R: DbTx>(
&self,
source_tx: &R,
) -> Result<(), DatabaseError>
fn import_table<T: Table, R: DbTx>( &self, source_tx: &R, ) -> Result<(), DatabaseError>
Imports all table data from another transaction.
Sourcefn 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>
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>
Imports table data from another transaction within a range.
This method works correctly with both regular and DupSort tables. For DupSort tables,
all duplicate entries within the range are preserved during import.
Sourcefn import_dupsort<T: DupSort, R: DbTx>(
&self,
source_tx: &R,
) -> Result<(), DatabaseError>
fn import_dupsort<T: DupSort, R: DbTx>( &self, source_tx: &R, ) -> Result<(), DatabaseError>
Imports all dupsort data from another transaction.
Dyn Compatibility§
This trait is not dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
