安装

cargo add quick-kv

示例

use quick_kv::prelude::*;

fn main() -> anyhow::Result<()>
{
    let mut client = QuickClient::<String>::new(None);

    client.get("star this repo")?;

    Ok(())
}

CLI (Beta)

Quick-KV 随附用于与数据库交互的 REPL。

要安装 CLI，请运行以下命令

cargo install quick-kv

这与 cargo add 命令不同，因为它全局安装 CLI，允许您将其作为可执行文件使用。

lib.rs:

QuickKV 是一个简单、快速、易于使用的键值存储。

功能

• 简单 API
• 内置日志记录
• I/O 缓存
• CLI 工具（Beta）
