Trait DbDupCursorRW

pub trait DbDupCursorRW<T: DupSort> {
    // Required methods
    fn delete_current_duplicates(&mut self) -> Result<(), DatabaseError>;
    fn append_dup(
        &mut self,
        key: T::Key,
        value: T::Value,
    ) -> Result<(), DatabaseError>;
}

Required Methods

fn delete_current_duplicates(&mut self) -> Result<(), DatabaseError>

Delete all duplicate entries for current key.

fn append_dup( &mut self, key: T::Key, value: T::Value, ) -> Result<(), DatabaseError>
