Options contains general parameters for a LevelDB instance. Most of the names are self-explanatory; the defaults are defined in the Default implementation.

Fields

cmp: Rc<Box<dyn Cmp>>

env: Rc<Box<dyn Env>>

log: Option<Rc<RefCell<Logger>>>

create_if_missing: bool

error_if_exists: bool

paranoid_checks: bool

write_buffer_size: usize

max_open_files: usize

max_file_size: usize

block_cache: Rc<RefCell<Cache<Block>>>

block_size: usize

block_restart_interval: usize

compressor: u8

Compressor id in compressor list

Note: you have to open a database with the same compression type as it was written to, in order to not lose data! (this is a bug and will be fixed)

compressor_list: Rc<CompressorList>

reuse_logs: bool

reuse_manifest: bool

filter_policy: Rc<Box<dyn FilterPolicy>>

Trait Implementations

impl Clone for Options

fn clone(&self) -> Options

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Default for Options

fn default() -> Options

Returns the “default value” for a type.
