先决条件

snappy 和 leveldb 需要安装。在Ubuntu上，我推荐

sudo apt-get install libleveldb-dev libsnappy-dev

使用

如果你的项目使用 Cargo，在你的 Cargo.toml 中添加以下行

[dependencies]

leveldb-minimal = "0.1"

开发

确保你已经安装了所有先决条件。运行

$ cargo build

进行构建和

$ cargo test

运行测试套件。

示例

extern crate tempdir;
extern crate leveldb;

use tempdir::TempDir;
use leveldb::database::Database;
use leveldb::iterator::Iterable;
use leveldb::kv::KV;
use leveldb::options::{Options,WriteOptions,ReadOptions};

fn main() {
  let tempdir = TempDir::new("demo").unwrap();
  let path = tempdir.path();

  let mut options = Options::new();
  options.create_if_missing = true;
  let mut database = match Database::open(path, options) {
      Ok(db) => { db },
      Err(e) => { panic!("failed to open database: {:?}", e) }
  };

  let write_opts = WriteOptions::new();
  match database.put(write_opts, &[1], &[1]) {
      Ok(_) => { () },
      Err(e) => { panic!("failed to write to database: {:?}", e) }
  };

  let read_opts = ReadOptions::new();
  let res = database.get(read_opts, &[1]);

  match res {
    Ok(data) => {
      assert!(data.is_some());
      assert_eq!(data, Some(vec![1]));
    }
    Err(e) => { panic!("failed reading data: {:?}", e) }
  }

  let read_opts = ReadOptions::new();
  let mut iter = database.iter(read_opts);
  let entry = iter.next();
  assert_eq!(
    entry,
    Some((vec![1], vec![1]))
  );
}
