Struct rocks::options::Options

pub struct Options { /* fields omitted */ }

Options to control the behavior of a database (passed to DB::Open)

use rocks::options::Options;

let _opt = Options::default()
          .map_db_options(|db| db.create_if_missing(true))
          .map_cf_options(|cf| cf.disable_auto_compactions(true));

Implementations

impl Options

pub fn default_instance() -> &'static Options

default Options with create_if_missing = true

pub fn new(
    dbopt: Option<DBOptions>,
    cfopt: Option<ColumnFamilyOptions>
) -> Options

pub fn to_cf_options(&self) -> ColumnFamilyOptions

pub fn to_db_options(&self) -> DBOptions

pub fn map_db_options<F: FnOnce(DBOptions) -> DBOptions>(self, f: F) -> Self

Configure DBOptions using builder style.

pub fn map_cf_options<F: FnOnce(ColumnFamilyOptions) -> ColumnFamilyOptions>(
    self,
    f: F
) -> Self

Configure ColumnFamilyOptions using builder style.

pub fn prepare_for_bulk_load(self) -> Self

Set appropriate parameters for bulk loading.

All data will be in level 0 without any automatic compaction. It's recommended to manually call CompactRange(NULL, NULL) before reading from the database, because otherwise the read can be very slow.

pub fn optimize_for_small_db(self) -> Self

Use this if your DB is very small (like under 1GB) and you don't want to spend lots of memory for memtables.
