redis_rocksdb

rust implement structure kv(key/value) embedded database, storage by rocksdb
Feature list
1. redis list 2. Object, key+field 3. ObjectBit, a bit object 4. Max/Min binary heap(zero copy) 5. B + Tree (Binary plus Tree) ...

Sample

more details see the test
Max Heap
```rust use rocksdb::TransactionDB; use redis_rocksdb::{Heap, RedisRocksdb, WrapTransactionDB};

fn sample(){ let transdb= TransactionDB::opendefault("dbname.db").expect(""); let redisdb = RedisRocksdb::new(transdb); let wrapdb = WrapTransactionDB { db: redisdb.getdb() };

let max_heap = RedisRocksdb::max_heap();
let key = vec![0 as u8, 1, 2];
let field = vec![6 as u8, 7, 8];
let value = "data".to_owned();

let _ = max_heap.push(&wrap_db, &field, value.as_bytes());
let _ = max_heap.pop(&wrap_db, &key);

} Object rust use rocksdb::TransactionDB; use redis_rocksdb::{Heap, Object, RedisRocksdb, WrapTransactionDB};

fn sample(){ let transdb= TransactionDB::opendefault("dbname.db").expect(""); let redisdb = RedisRocksdb::new(transdb); let wrapdb = WrapTransactionDB { db: redisdb.getdb() };

let object = RedisRocksdb::object();
let key = vec![0 as u8, 1, 2];
let field = vec![6 as u8, 7, 8];
let value = "data".to_owned();

let _ = object.set(&wrap_db, &field, value.as_bytes());
let _ = object.get(&wrap_db, &key, &field);

} ```

Install

Window

1. install llvm
2. Environment value: set LIBCLANG_PATH=E:/lang/LLVM/lib --- sometimes need to restart the window system for clion

   Linux

See:

ssdb-rocks(c++)
ssdb
rust-rocksdb, no transaction
ckb-rocksdb, transaction

注：在v0.1.0版本时使用ckb-rocksdb，在v0.2.0版本中，为了减少一次函数调用，把事务与非事务分别使用不同的接口实现，所以就没有必要再使用ckb-rocksdb
