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.

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.
