Struct DBConfig

pub struct DBConfig {
    pub path: PathBuf,
    pub cache_size: Option<usize>,
    pub options: HashMap<String, String>,
    pub options_file: Option<PathBuf>,
}

Database config options.

Fields

path: PathBuf

Database directory path.

By default, it is a subdirectory inside the data directory.

cache_size: Option<usize>

The capacity of RocksDB cache, which caches uncompressed data blocks, indexes and filters, default is 128MB

options: HashMap<String, String>

Provide RocksDB options.

More details can be found in the official tuning guide.

options_file: Option<PathBuf>

Provide an options file to tune RocksDB for your workload and your system configuration.

More details can be found in the official tuning guide.

Implementations

impl Config

pub fn adjust<P: AsRef<Path>>( &mut self, root_dir: &Path, data_dir: P, name: &str, )

Canonicalizes paths in the config options.

If self.path is not set, set it to data_dir / name.

If self.path or self.options_file is relative, convert them to absolute path using root_dir as current working directory.

Trait Implementations

impl Clone for Config

fn clone(&self) -> Config

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Config

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Config

fn default() -> Config

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Config

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for Config

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
