query

概述

query 是一个简化的单表数据库库

示例

// get some data to work with
let data = (0..10).collect();

// write the data to disk
let mut db = DB::create("test.db", data)
    .expect("can't create 'test.db'");

// change the data in memory
db.iter_mut()
	.for_each(|i| *i * 2);

// apply the changes
db.apply()
	.expect("can't update 'test.db'");

// delete the data in memory
drop(db);

// read the database from memory
let db = DB::load("test.db")
	.expect("can't read 'test.db'");

// all values have been multiplied by 10
assert_eq!(db.to_vec(), (0..100).step_by(10).collect());

此软件包提供非常简单数据库的功能，您只能有一个数据库中的表，您不能就地更改数据，必须将整个数据库加载到内存中。但它非常简单。
