pub struct Options {
    pub create_if_missing: bool,
    pub error_if_exists: bool,
    pub paranoid_checks: bool,
    pub write_buffer_size: Option<size_t>,
    pub max_open_files: Option<i32>,
    pub block_size: Option<size_t>,
    pub block_restart_interval: Option<i32>,
    pub compression: Compression,
    pub cache: Option<Cache>,
}

Options to consider when opening a new or pre-existing database.

Note that in contrast to the leveldb C API, the Comparator is not passed using this structure.

For more detailed explanations, consider the leveldb documentation
