Required Methods§

source

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

Provided Methods§

source

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

source

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
