Required Methods

fn get_raw_iter_cf<'a: 'b, 'b>( &'a self, cf_handle: &ColumnFamily, readopts: &ReadOptions, ) -> Result<DBRawIterator<'b>, Error>

Provided Methods

fn get_iter_cf<'a: 'b, 'b>( &'a self, cf_handle: &ColumnFamily, readopts: &ReadOptions, mode: IteratorMode<'_>, ) -> Result<DBIterator<'b>, Error>

fn iterator_cf_opt<'a: 'b, 'b>( &'a self, cf_handle: &ColumnFamily, mode: IteratorMode<'_>, readopts: &ReadOptions, ) -> Result<DBIterator<'b>, Error>

Opens an interator using the provided ReadOptions. This is used when you want to iterate over a specific ColumnFamily with a modified ReadOptions

fn iterator_cf<'a: 'b, 'b>( &'a self, cf_handle: &ColumnFamily, mode: IteratorMode<'_>, ) -> Result<DBIterator<'b>, Error>

fn full_iterator_cf<'a: 'b, 'b>( &'a self, cf_handle: &ColumnFamily, mode: IteratorMode<'_>, ) -> Result<DBIterator<'b>, Error>

fn prefix_iterator_cf<'a: 'b, 'b>( &'a self, cf_handle: &ColumnFamily, prefix: &[u8], ) -> Result<DBIterator<'b>, Error>

fn raw_iterator_cf<'a: 'b, 'b>( &'a self, cf_handle: &ColumnFamily, ) -> Result<DBRawIterator<'b>, Error>
