Rust wrapper for RocksDB.

Examples

use ckb_rocksdb::prelude::*;
# use ckb_rocksdb::TemporaryDBPath;
// NB: db is automatically closed at end of lifetime

let path = "_path_for_rocksdb_storage";
# let path = TemporaryDBPath::new();
# {

let db = DB::open_default(&path).unwrap();
db.put(b"my key", b"my value").unwrap();
match db.get(b"my key") {
Ok(Some(value)) => println!("retrieved value {}", value.to_utf8().unwrap()),
Ok(None) => println!("value not found"),
Err(e) => println!("operational problem encountered: {}", e),
}
db.delete(b"my key").unwrap();
# }

Opening a database and a single column family with custom options:

use ckb_rocksdb::{prelude::*, ColumnFamilyDescriptor};
# use ckb_rocksdb::TemporaryDBPath;

let path = "_path_for_rocksdb_storage_with_cfs";
# let path = TemporaryDBPath::new();

let mut cf_opts = Options::default();
cf_opts.set_max_write_buffer_number(16);
let cf = ColumnFamilyDescriptor::new("cf1", cf_opts);

let mut db_opts = Options::default();
db_opts.create_missing_column_families(true);
db_opts.create_if_missing(true);
# {
let db = DB::open_cf_descriptors(&db_opts, &path, vec![cf]).unwrap();
# }
