Available on crate feature provider only.

Allows duplicating tables across databases

Provided Methods

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

where T: Table, R: DbTx,

Imports all table data from another transaction.

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

where T: Table, R: DbTx, <T as Table>::Key: Default,

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.

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

where T: DupSort, R: DbTx,

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.
