Struct rocksdb::ReadOptions

pub struct ReadOptions { /* fields omitted */ }

Methods

impl ReadOptions

pub fn set_iterate_upper_bound<K: AsRef<[u8]>>(&mut self, key: K)

Set the upper bound for an iterator, and the upper bound itself is not included on the iteration result.

pub fn set_prefix_same_as_start(&mut self, v: bool)

pub fn set_total_order_seek(&mut self, v: bool)

pub fn set_readahead_size(&mut self, v: usize)

If non-zero, an iterator will create a new table reader which performs reads of the given size. Using a large size (> 2MB) can improve the performance of forward iteration on spinning disks. Default: 0

use rocksdb::{ReadOptions};

let mut opts = ReadOptions::default();
opts.set_readahead_size(4_194_304); // 4mb
