Struct sstable::Options

pub struct Options {
    pub cmp: Arc<Box<dyn Cmp>>,
    pub write_buffer_size: usize,
    pub block_cache: Arc<RwLock<Cache<Block>>>,

Options contains general parameters for reading and writing SSTables. Most of the names are self-explanatory; the defaults are defined in the Default implementation.

Fields

cmp: Arc<Box<dyn Cmp>>

write_buffer_size: usize

block_cache: Arc<RwLock<Cache<Block>>>

block_size: usize

block_restart_interval: usize

compression_type: CompressionType

filter_policy: BoxedFilterPolicy

Implementations

impl Options

pub fn with_cache_capacity(self, capacity: usize) -> Options

Configure to use a custom block cache capacity. The capacity is given as number of items in the cache and the minimal allowed capacity is 1.

fn clone(&self) -> Options

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
