Required Methods§

source

fn get_raw_iter<'a: 'b, 'b>( &'a self, readopts: &ReadOptions ) -> DBRawIterator<'b>

Provided Methods§

source

fn get_iter<'a: 'b, 'b>( &'a self, readopts: &ReadOptions, mode: IteratorMode<'_> ) -> DBIterator<'b> ⓘ

source

fn iterator_opt<'a: 'b, 'b>( &'a self, mode: IteratorMode<'_>, readopts: &ReadOptions ) -> DBIterator<'b> ⓘ

source

fn iterator<'a: 'b, 'b>(&'a self, mode: IteratorMode<'_>) -> DBIterator<'b> ⓘ

source

fn full_iterator<'a: 'b, 'b>(&'a self, mode: IteratorMode<'_>) -> DBIterator<'b> ⓘ

Opens an interator with set_total_order_seek enabled. This must be used to iterate across prefixes when set_memtable_factory has been called with a Hash-based implementation.

source

fn prefix_iterator<'a: 'b, 'b>(&'a self, prefix: &[u8]) -> DBIterator<'b> ⓘ

source

fn raw_iterator<'a: 'b, 'b>(&'a self) -> DBRawIterator<'b>
